The Dallas Cowboys will be without defensive end David Irving for the first four games this season.
The NFL officially suspended Irving on Wednesday for violating the league's performance-enhancing substances policy.
Irving, 23, is eligible to participate in off-season and preseason practices and games. The earliest he can play in the regular season will be the Week 5 game vs. the Green Bay Packers on Oct. 8 at AT&T Stadium.
This is a blow to the Cowboys defensive line, a unit the organization continues to try and improve.
Irving had four sacks a season ago, and was credited with a team-high 26 quarterback pressures in 15 games.
