Dallas Cowboys defensive end David Irving is facing a four-game suspension for violation of the league's performance-enhancing drug policy, according to a source.
It's a huge setback for Irving's development and the Cowboys pass rush.
Irving was the team's best pass rusher at the end of last season, making plays from end and tackle. He hoped to build on that momentum in 2017.
Now he is gone for the first four, barring a reversal on appeal.
The Cowboys drafted defensive end Taco Charlton in the first round to bolster an already suspect pass rush but were still counting on the blossoming 23-year old Irving, who had three sacks in two games last December.
