The Dallas Cowboys' pass rush could be down another player to open the season.
NFL Network Insider Ian Rapoport reports defensive lineman David Irving is facing a four-game suspension for violation of the league's performance-enhancing drug policy, according to a source. The issue stems from a supplement Irving had a marketing deal with, per Rapoport.
Mike Fisher of 105.3 The Fan in Dallas first reported the development.
Irving is appealing the suspension, per Rapoport.
Irving came on strong down the stretch last season, morphing into the Cowboys' best pass rusher. The 23-year-old notched four sacks in 2016, including three in a two-game stretch in December.
The Cowboys added to their pass rush with first-round pick Taco Charlton, and are expected to get Demarcus Lawrence back healthy, but if Irving's suspension isn't overturned, it's a big blow for a thin group to open the season.
