  Mr-. Justice Clark
  delivered the opinion of the Court.
  This is a negligence case under the Federal Employers’ Liability Act, 35 Stat. 65, 45 U. S. C. § 51. Petitioner, an employee of respondent, was injured while shifting various railroad cars on its tracks in and about the Ford Motor Company plant at Norfolk, Virginia. His first cause of action charged respondent with negligence in requiring the shifting of the cars in such an accelerated time and with such inexperienced help that petitioner was injured in attempting to carry out his instructions. In his second claim petitioner alleged that the physician furnished petitioner by respondent subsequent to his injury administered him improper treatment, thus aggravating his injury, and that respondent was responsible for such negligence. At the close of the case, the trial judge sustained the motion of respondent to strike petitioner’s evidence and discharged' the jury. On petition for writ of error claiming that the issues should have been presented to the jury, the Virginia Supreme Court of Appeals rejected'the petition and, in effect; affirmed the judgment, without written opinion. Believing that the question posed was of importance in the uniform administration of this federal statute, we granted certiorari. 359 U. S. 964. We conclude that the issue of negligence as to the injury should have been submitted to the jury, but that the evidence was insufficient to support the malpractice claim.
  Petitioner was a yard conductor .for respondent. On July 3,1957, he was instructed to “shift” or “spot” various railway cars to a loading platform on a spur track of the Ford Motor Company at Norfolk. There were 43 cars involved. Some were empty and standing at the loading tracks at the plant. These had to be moved out to make way for the loaded cars which were outside the plant in respondent’s shifting yards. The job called for them to be lined up and then moved to particular positions or spots on the tracks at the loading platform in the plant where Ford employees might remove their contents. On the morning of the accident there were designated at the Ford loading platform some 22 spots to which the -loaded cars were to be switched. Two brakemen were assigned to assist petitioner in the operation. Petitioner was to complete the spotting during the lunch period sat the Ford plant, which was 30 minutes. The evidence shows that neither of the brakemen' assigned to petitioner was experienced in this particular operation. The senior brakeman had never spotted cars at the plant before, nor had he worked as a senior brakeman. The other brakeman had spotted cars at the plant for only a- short period. Railroad employees classed the Ford “switching operation” as “a hot job” because “you do your job a little faster there than you would in the yard.” In the opinion of brakemen who had spotted' cars there, the minimum time for completion of an operation involving this many cars was 50 minutes, and the maximum well over an hour. Since petitioner was instructed to perform the task in 30 minutes, it was necessary for him to work faster than he normally would. In addition, the senior brakeman had informed petitioner of his inexperience, which required petitioner to take a position on top of the boxcars in order to be ready to assist the brakemen. Normally, petitioner would have taken his position on the ground where a conductor, such as he, usually carried out his assigned duties. When one of the brakemen called for assistance in the spotting operation, petitioner ran along the top- of the boxcars toward the brakeman to give him help, but, upon coming to a gondola car, was obliged to descend the ladder of the boxcar next to it. Petitioner slipped on the ladder and fell to thé ground, suffering the injury complained of here.
  The record indicates that petitioner would have taken his position on the ground rather than on the railroad cars but for the inexperience of the brakemen. This required petitioner to take his position on top of the cars in order to assist the brakemen — a function not ordinarily performed by a yard conductor. We think it should have been left to the jury to decide whether the respondent’s direction to complete the spotting operation within 30 minutes, plus the inexperience of the brakemen assigned to perform this “hot job,” might have precipitated petitioner’s injury. “The debatable quality of that issue, the fact that fair-minded men might reach different conclusions, emphasize the appropriateness of leaving the ques-tiqn to the jury. The jury is the tribunal under our legal system to decide that type of issue (Tiller v. Atlantic Coast Line R. Co. [318 U. S. 54]) as well as issues involving controverted evidence. Jones v. East Tennessee, V. & G. R. Co., 128 U. S. 443, 445; Washington & Georgetown R. Co. v. McDade, 135 U. S. 554, 572. To withdraw such a question from the jury is to usurp its functions.” Bailey v. Central Vermont R. Co., 319 U. S. 350, 353-354 (1943).
  As to the malpractice claim, the trial court held that the railroad would not be liable for any negligence on the part of Dr. Leigh, the physician it furnished petitioner. We need not pass on this issue, however, since we find no evidence sufficient to support a malpractice recovery. Proof of malpractice, in effect, requires two evidentiary steps: evidence as to the recognized standard of the medical community in the particular kind of case, and a showing that the physician in question negligently departed from this standard in his treatment of plaintiff. The trial judge acknowledged these to be the tests of malpractice and allowed petitioner’s counsel to make an offer of proof, although ruling that the railroad was nob responsible for Dr. Leigh’s actions. The evidence shows that the physician was of unquestioned qualification and treated petitioner in accordance with his best medical judgment and long practice. The only evaluation concerning his treatment was that of Dr. Thiemeyer, another physician who had treated petitioner, who testified that he did not “think that [the treatment] is proper.” Dr. Thiemeyer’s opinion was that “a fracture should be immobilized until it is healed sufficiently to bear weight without jeopardy of its healing,” and that he “would say that activity would aggravate this fracture in that period.” This offer of proof was fatally deficient. No foundation was laid as to the recognized medical standard for the treatment of such a fracture. No standard having been established, it follows that the offer of proof was not sufficient. The trial judge; therefore, was correct in declining to submit the malpractice claim to the jury.
  In view of our holding on the first cause of action, the judgment is reversed and the case is remanded for further proceedings not inconsistent with this opinion.
  It is so ordered.
  For the reasons set forth in his opinion in Rogers v. Missouri Pacific R. Co., 352 U. S. 500, 524, Mr. Justice Frankfurter is of the view that the writ of certiorari was improvidently granted.
  While the evidence indicates that this fact is undisputed, if the evidence is in conflict, such an issue is of course for the jury.
