PER CURIAM:
Under the recent opinion of the Supreme Court of the United States in the case of Richardson, Secretary of Health, Education, and Welfare v. Perales, 402 U.S. 389, 91 S.Ct. 1420, 28 L. Ed.2d 842, decided May 3, 1971, the conclusion of the District Court that the testimony of Dr. C.W. Williams, the orthopedic surgeon, and Dr. R.C. Hardy, the neurosurgeon, did not constitute substantial evidence was error. Therefore, the Secretary's determination, being supported by substantial evidence, must be affirmed, even if there was also substantial evidence which may have supported a finding in favor of the claimant Grant. Moreover, the resolution of any conflict in the evidence, including conflicting medical opinions, as in the case at hand, and the determination of questions of credibility of the witnesses are not for the court; such functions are solely within the province of the Secretary. Martin v. Finch, 5 Cir., 1969, 415 F.2d 793; Stillwell v. Cohen, 5 Cir., 1969, 411 F.2d 574, 575-576.
The motion of the defendant, Secretary of Health, Education and Welfare, should be granted; and the motion of the plaintiff (claimant) for summary judgment should be denied.
Reversed with directions.
