Dallas Cowboys defensive end David Irving is reportedly facing a four-game suspension for testing positive for a banned substance.
Mike FIsher of 105.3 The Fan was told that Cowboys officials planned to meet with Irving on Tuesday to discuss the possibility that he failed a drug test for supplements. Ian Rapoport of NFL Media later confirmed the report, noting that the supplement Irving took was related to a marketing deal he has.

Irving, who was ejected from a game last season because of a fight, is reportedly not in the NFL’s drug program. However, that would not prevent him from avoiding a four-game suspension. The 23-year-old is expected to appeal.
Irving had four sacks, four forced fumbles and five passed defensed in 15 games last season.
