Winston threw impressively at the combine on Saturday and insisted in his media interview that he felt fine.
NFL Media Insider Ian Rapoport reported Friday that weakness around a nerve in Winston's shoulder was detected by a doctor during his combine medical exam, and that he went to the hospital for additional testing. Winston's baseball career was apparently the culprit. Winston pitched as a closer out of the bullpen for the FSU baseball team and compiled a 1.08 ERA over 33 innings for the Seminoles last year.
According to Breer, the condition of Winston's shoulder is normal for pitchers, and Winston hasn't had a typical offseason football recovery.
Winston is expected to be drafted long before the Cowboys pick at No. 27, but nobody can say the club doesn't do its due diligence in evaluating the draft's top quarterbacks. At last year's combine, Dallas made Texas A&M quarterback Johnny Manziel one of its 60 formal combine interviews, and Cowboys owner Jerry Jones was not pleased that the team missed out on Manziel in the draft.
