Opinion by

Hoover’s Sani-Dairy Products (Hoover) and its insurer appeal a decision of the Workmen’s Compensation Appeal Board (Board) which affirmed a referee ’s decision to reinstate benefits to claimant Francis Nagle.

The claimant injured his back while performing services for Hoover on March 20, 1978 and was paid benefits under a supplemental agreement entered into between the parties on May 23, 1978 for total disability. On December 4, 1978 he accepted a job1 with Shaner Brothers Oil Company (Shaner Brothers) which required no heavy lifting and his benefits were then suspended. On March 5, 1979, however, he quit this job and soon thereafter filed the instant reinstatement petition alleging that he could not perform his duties at Shaner Brothers because of a recurrence of *576his March 20,1978 injury at Hoover’s. Hoover, on the other hand, alleged that it was relieved of responsibility because a new injury had occurred while the claimant was employed by Shaner Brothers.2 The referee, relying on the testimony of the claimant’s physician, found that the claimant did in fact establish that he had a recurrence of the March 20, 1978 injury and accordingly granted benefits. The Board, without taking additional evidence, affirmed.

Where, as here, the party with the burden3 of proof has prevailed below, our scope of review is limited to a determination of whether or not constitutional rights were violated, an error of law was committed, or the referee’s findings of fact were unsupported by substantial evidence. United States Steel Corp. v. Workmen’s Compensation Appeal Board, 52 Pa. Commonwealth Ct. 641, 416 A.2d 619 (1980).

Hoover argues that the necessary findings of fact regarding whether or not the claimant actually had a recurrence of his original injury were unsupported by substantial evidence. Our careful review of the record, however, discloses that the claimant’s physician, who had also treated him for his original (Maroh 20,1978) injury, unequivocally4 testified that he carefully es*577amined the claimant on April 9, 1979 and concluded that the claimant had had a recurrence of the symptoms he previously exhibited on March 20, 1978.

Hoover next argues that the referee violated its constitutional rights by prematurely closing the record and refusing to grant it a continuance, specifically charging that such action precluded it from securing the testimony of one Mr. Shaner, who was in poor health, and that such testimony would have shown the degree of effort involved by the claimant in his Shaner Brothers’ job. We have recognized, of course, that due process principles are not violated by workmen’s compensation authorities when they exercise their discretion to deny a requested continuance where an employer had sufficient means and ample time within which it could have accomplished what it says it could accomplish if a continuance were granted. Mrs. Smith Pie Co. v. Workmen’s Compensation Appeal Board, 57 Pa. Commonwealth Ct. 274, 426 A.2d 209 (1981); see Workmen’s Compensation Appeal Board v. Basalyga, 24 Pa. Commonwealth Ct. 345, 355 A.2d 603 (1976). Here, the record reveals that the referee was most accommodating and did continue this case several times5 so that Mr. Shaner could be deposed by Hoover, but Ploover failed to depose him. Moreover, Hoover could have but did not subpoena Mr. Shaner nor did it establish or aver in seeking the continuance that the information which it sought from Mr. Shaner could be ascertained only from him and not from his brother and operating partner, from the claimant’s co-workers, or from Shaner Brothers’ records.

We believe, therefore, that the referee did not abuse his discretion in denying Hoover’s request to protect further this matter. And, finding no error of *578law or necessary fact unsupported by substantial evidence, we will accordingly affirm tbe order of tbe Board.6
