Dallas Cowboys defensive tackle David irving has been suspended four games for violating the NFL’s policy on substances of abuse.

According to Ian Rapoport of the NFL Network, Irving will miss the first four games of the 2018 season but is eligible to take take part in al offseason workouts and practices. He’ll be able to return to the roster on Oct. 1.

The 24-year-old pass rusher was also suspended for the first four games of the 2017 season for violating the league’s policy on performance enhancing drugs. This latest suspension is yet another hurdle in what’s been a tumultuous career for Irving. In April, he was accused of domestic violence by a former girlfriend after she reportedly hacked his Twitter account. She’s since walked back her statements to Frisco police and the case is now closed.

“There’s more to my life than just football,” Irving said about the allegations. “I’m actually a real person. I have family issues, a lot of issues I’ve been dealing with. I can’t go into much detail. Just know it’s behind me. By the time the season starts, I won’t be dealing with any of this BS anymore.”

Irving’s suspension leaves a significant hole in the Cowboys defensive line as the second-year player totaled 7 sacks in just eight games last season and four in his rookie campaign. An undrafted free agent who was signed by Dallas via the Kansas City Chiefs practice squad in 2015, Irving signed a $2.91 million restricted free-agent tender in April.
