Family members filed this medical malpractice action in federal district court following the death of Hiram Fernandez, and a jury ultimately found for the health care defendants. On appeal, plaintiffs challenge several trial court rulings, including the denial of their motion for new trial. We affirm the district court judgment.

BACKGROUND

On November 4, 1991, Hiram Fernandez was taken to the emergency room of Federico Trilla Hospital in Carolina, Puerto Rico, after awakening with chest pains, severe leg cramps, and vomiting. The 64-year-old Fernandez informed Dr. Pedro Rivera Bermudez (“Dr. Rivera”) that the chest pain had stopped after he vomited, but the severe leg pain had not abated. Fernandez failed to tell Dr. Rivera that he was taking medication for both asthma and hypertension. Since Fernandez did not complain of recurring chest pain, and his vital statistics were within normal or borderline range, Dr. Rivera tentatively diagnosed a pinched nerve but nonetheless ordered an electrocardiogram (EKG), a urinalysis, and an x-ray of the lumbosacral region and the left leg. All tests were negative.

A few hours later, Dr. Rivera was relieved in the emergency room by Dr. Ricardo Martinez Cortinez (“Dr. Martinez”) whose examination confirmed that Fernandez was in stable condition, with no complaints of chest pain. As a blood test showed a slightly elevated white blood count, Dr. Martinez ordered a second urinalysis, as well as a chest x-ray, to rule out any urinary or pulmonary infection which might have been caused by the vomiting. The chest x-ray coineidently revealed that Fernandez had a dilated aorta, which Dr. Martinez attributed to normal borderline hypertension in a patient of Fernandez’ age, rather than an emergent symptom of aortal dissection, a condition usually accompanied by excruciating and unrelenting chest pain, fainting spells, profuse sweating, and tachycardia. Like Dr. Rivera, Dr. Martinez diagnosed a pinched nerve. Shortly thereafter Dr. Martinez referred Fernandez to a neuropathic specialist, and discharged him.

The next day, when Fernandez was unable to recognize family members, he was taken to his personal physician, Dr. Abelardo Vargas, who performed a physical examination and another EKG (also negative), and ordered an upper gastrointestinal series to determine whether there was a hiatal hernia. The next day, on his way to undergo these tests, Fernandez collapsed and died. An autopsy revealed the cause of death as a dissected aorta, a condition treatable with surgery in more than 90% of cases.

The decedent’s spouse, children, and grandchildren filed a medical malpractice suit in federal district court pursuant to 28 U.S.C. § 1382 (diversity jurisdiction) against Drs. Rivera, Martinez, and Vargas, and against various insurers of the Federico Tril-la Hospital, including Global Insurance Company. Subsequently, Dr. Vargas was dismissed as a party defendant.

At trial, Dr. William T. Brown, a Miami-based cardiac specialist, provided expert testimony in behalf of plaintiffs on the applicable duty of care. Drs. Rivera and Martinez testified in their own defense, but presented no independent medical testimony. After the jury returned a verdict for all defendants, plaintiffs unsuccessfully filed a motion for new trial pursuant to Federal Rule of Civil Procedure 59, then brought this appeal.

DISCUSSION

Appellants challenge four trial court rulings. First, they focus on the denial of their request for rebuttal to the closing argument made by the defense. Although trial court rulings on the conduct, timing, and ordering of closing arguments are reviewed only for abuse of discretion, see Bonilla v. Yamaha Motors Corp., 955 F.2d 150, 155 (1st Cir.1992); see also United States v. Wood, 982 F.2d 1, 4 (1st Cir.1992), appellants insist that civil-action plaintiffs have an absolute right to rebut the closing argument of the defense. See Martin v. Chesebrough-Pond’s, Inc., 614 F.2d 498 (5th Cir.1980) (noting that “[njormally the party with the burden of proof has the right to open and close,” but holding that a particular codefendant had no right to rebuttal as against another codefend-ant where the two had asserted mutual cross-claims).

Appellants are mistaken. The Martin court did not describe a civil-action plaintiffs “right” to rebuttal as absolute, but merely reconfirmed that the decision to permit rebuttal is a procedural matter which rests within the sound discretion of the trial judge, id. at 501, and rarely (if ever) provides fertile ground for appeal. See Lancaster v. Collins, 115 U.S. 222, 225, 6 S.Ct. 33, 34-35, 29 L.Ed. 373 (1885); Montwood Corp. v. Hot Springs Theme Park, 766 F.2d 359, 364 (8th Cir.1985); Moreau v. Oppenheim, 663 F.2d 1300, 1311 (5th Cir.1981), cert. denied, 458 U.S. 1107, 102 S.Ct. 3486, 73 L.Ed.2d 1368 (1982); Commercial Iron & Metal Co. v. Bache Halsey Stuart, Inc., 581 F.2d 246, 249 (10th Cir.1978), cert. denied, 440 U.S. 914, 99 S.Ct. 1229, 59 L.Ed.2d 463 (1979).

Appellants further argue that rebuttal was vital to counteract the “inflammatory” statements made in argument by defense counsel, who portrayed, as inexplicable, plaintiffs’ voluntary dismissal of their claims against Dr. Vargas. Defense counsel argued to the jury that Dr. Vargas, the decedent’s long-time personal physician, was the one most likely to have been negligent since he was the last to treat Fernandez, and more familiar with his medical history. Defense counsel further argued that Dr. Vargas, like the defendant-physicians, had not suspected that the Fernandez symptoms indicated an incipient aor-tal dissection but rather a hiatal hernia. Appellants therefore contend that they were entitled to remind the jury in rebuttal that: (1)the defendants had the right to implead Dr. Vargas if they believed he was the only negligent party and the sole proximate cause of Fernandez’ death, and (2) Dr. Vargas had not treated Fernandez in a hospital; thus, unlike defendants, could not as readily have obtained a chest x-ray.

As plaintiffs failed to challenge the statements made by defense counsel in closing argument, we review only for plain error. See Johnson v. National Sea Prods., Ltd., 35 F.3d 626, 631 (1st Cir.1994). The statements made by the defense in closing were in no sense inflammatory, but rather a measured response to earlier observations by plaintiffs’ counsel that “Dr. Vargas [is not] responsible for anything here simply because he did not have the x-rays that these defendants had the benefit of having because he was not in a position of having a full clinical picture.” Indeed, plaintiffs not only invited the defense response they now claim gave rise to a vital need for rebuttal, but their invitation was itself a sufficient “reminder” to the jury that plaintiffs had adduced evidence that Dr. Vargas did not treat Fernandez in a hospital setting where x-rays were readily obtainable. Thus, the district court ruling was well within its sound discretion.

In addition, though Fed.R.Civ.P. 14(a) permits defendants to implead a joint tort-feasor, see also Reyes-Lopez v. Misener Marine Constr. Co., 854 F.2d 529, 535 n. 23 (1st Cir.1988) (citing to Puerto Rico ease law allowing joint-tortfeasor contribution), Rule 14 is not mandatory. Appellants do not cite, nor have we found, any authority for the proposition that a jury must be permitted to draw an adverse inference from a defendant’s decision to forego a Rule 14 impleader. We therefore conclude that there was no plain error.

Second, appellants claim that it was an abuse of discretion to refuse their timely request to instruct the jury that defendants could have impleaded Dr. Vargas. For the reasons discussed above, we find no abuse of discretion. See Makuc v. American Honda Motor Co., 835 F.2d 389, 393 n. 1 (1st Cir.1987) (noting that proponent must cite to some legal authority which would support its proposed jury instruction).

Third, appellants contend that over-repetition of the district court’s unexceptionable jury instruction — that plaintiffs must establish all elements of their negligence claims— constituted reversible error because it exaggerated the burden of proof in the minds of the jury. See United States v. Assi, 748 F.2d 62, 66 (2d Cir.1984). Similar reversible error arose, plaintiffs say, from the district court’s over-repetition of its “error in judgment” instruction, viz., that a physician is not liable under Puerto Rico law for a faulty diagnosis or failure to treat if there existed “a reasonable or educated doubt as to the [appropriate] medical course to [have] follow[ed].” Once again, we must disagree.

As appellants failed to object to the burden-of-proof instructions before the jury retired to deliberate, see Fed.R.Civ.P. 51, we review for plain error. See Kerr-Selgas v. American Airlines, Inc., 69 F.3d 1205, 1213 (1st Cir.1995). Even though there may be a threshold beyond which further repetition of an otherwise proper jury instruction creates an unacceptable risk that the jury will be misled, see Davet v. Maccarone, 973 F.2d 22, 26 (1st Cir.1992), appellants do not approach such a showing by citing three brief references to the burden of proof in the eleven-page jury charge.

Similarly, though plaintiffs asserted a contemporaneous objection to the “multiple” error-in-judgment instructions, there was no error. A correct understanding of the error-in-judgment principle, the seminal legal concept defining the duty of care incumbent upon physicians under Puerto Rico medical malpractice law, was vital to a proper jury verdict. Moreover, the trial court’s error-in-judgment instructions, individually and in combination, were neither suggestive nor prejudicial.

Finally, appellants claim that the district court erred in denying their motion for new trial. See Fed.R.Civ.P. 59. Plaintiffs’ independent expert, Dr. Brown, testified that Drs. Rivera and Martinez were negligent in failing to record Fernandez’ past medical history on the hospital charts; and in failing to diagnose the aortal dissection on November 4, based on the complaints of earlier chest pain, and the chest x-ray disclosing aortal dilation. Appellants argue that the jury verdict was against the weight of the evidence because the duty of care in a malpractice action can only be proven through expert medical testimony; their expert, Dr. Brown, was the only independent medical expert to testify at trial; and the self-serving, biased testimony by the defendant-physicians themselves concerning their own duties of care was inherently untrustworthy.

A Rule 59 ruling, denying a motion for new trial based on an alleged insufficiency of evidence, is reviewed for abuse of discretion. See Lama v. Borras, 16 F.3d 473, 477 (1st Cir.1994). A new trial should be granted only :if the verdict, though rationally based on the evidence, “was so clearly against the weight of the evidence as to amount to a manifest miscarriage of justice.” Id. But where there is substantial evidence to support the verdict, it is “ ‘only in a very unusual case’ ” that denial of a Rule 59 motion will be ruled an abuse of discretion. Wagenmann v. Adams, 829 F.2d 196, 200 (1st Cir.1987) (citation omitted). This is not such a case.

At trial, plaintiffs had to establish: (1) the basic norms of knowledge and medical care applicable to general practitioners or specialists; (2) that the defendant-physicians did not meet these basic norms in their treatment of Fernandez; and (3) a causal relation between the defendants’ acts or omissions, and Fernandez’ death. See Rolon-Alvarado v. Municipality of San Juan, 1 F.3d 74, 77 n. 2 (1st Cir.1993). Although jurors rarely are able to determine the applicable standard of medical care without the benefit of expert testimony, under Puerto Rico law “there exists always a presumption that the treating physicians have observed a reasonable degree of care ... in the process of giving medical attention and treatment. [And] [p]laintiff bears the burden of refuting this presumption.” Id. at 78 (emphasis added). Thus, appellants’ premise — that malpractice defendants must invariably introduce independent expert testimony on the applicable duty of care — is flawed. Although defendant-physicians often do adduce independent expert testimony on the applicable standard of medical care, the jury’s implicit rejection of Dr. Brown’s testimony in this case was itself sufficient to support a verdict for defendants because of the rebuttable presumption of due care indulged under Puerto Rico law, see id.

The jury was not compelled to credit Dr. Brown’s testimony. “While not allowed to speculate, the factfinder is of course free to find some experts more credible than others.” Lama, 16 F.3d at 478. On cross-examination, Dr. Brown admitted that he was not able to read' or speak Spanish fluently, that he had not been provided initially with certified English translations of the hospital and medical records relating to Fernandez, and that until shortly before trial he had relied on informal translations — whose accuracy was seriously disputed at trial — prepared by his secretary and plaintiffs’ counsel. Given the infirmities in the only expert testimony presented by plaintiffs, there was no abuse of discretion in denying a new trial.

The district court judgment is affirmed. Costs are awarded to appellees. 
      
      . In fact, defense counsel expressly noted in closing argument: "This is the same Dr. Abelardo Vargas and I refer to this because brother counsel did refer to it [in his closing].”
     
      
      . Appellants also argue that no "error-in-judgment" instruction was appropriate because defendants failed to adduce expert medical testimony to support a jury finding that "a reasonable or educated doubt” existed. But see infra pp. 211-12.
     
      
      . For example, the hospital records stated that Fernandez had vomited before arriving at the hospital, and that this "ended” his chest pain, while the informal translations relied on by Dr. Brown merely indicated that the chest pain had "improved." In addition, presented with a medical treatise describing typical symptoms of an impending aortal dissection, Dr. Brown’s only response was the unexplicated assertion that he simply did not care what the medical treatise provided.
     
      
      . As concerns the contention by Dr. Brown that the defendant-physicians were negligent in failing to record Fernandez’ medical history on the medical charts, the jury was entitled to credit the defendant-physicians’ testimony that they left the "medical history” section of the hospital record blank because Fernandez informed them (inaccurately) that he had no significant medical history. See supra p. 209.
