Dallas Cowboys linebacker Rolando McClain has been suspended for four games for violating the league’s substance abuse policy. McClain will be reinserted to the team’s active roster after Week 4 of the upcoming 2015 NFL regular season.

The Cowboys officially announced the suspension and the 25-year-old released a statement about the development.

"I apologize to my family, the Cowboys organization, my teammates and Cowboys fans for my mistake," McClain said. "I will not break the rules of my profession in the future, and I regret my error. I look forward to returning to the field on week 5, when I hope to help my team beat the Patriots."

McClain, who will enter his sixth NFL season, was the eighth overall pick in the 2010 NFL Draft by the Oakland Raiders where he played from 2010 to 2013. He was part of the Baltimore Ravens’ offseason squad in 2013 and signed a one-year deal with the Cowboys in 2014.

While McClain will miss the first four games of the 2015 season, he will be allowed to join the offseason and preseason activities of the team.

Last season, McClain was credited 81 tackles, 1 sack and 2 interceptions in 13 games for the Cowboys. McClain injured his knee last season that caused him to miss this offseason’s organized team activities but reported to the team’s minicamp.
