Dallas Cowboys linebacker Rolando McClain has been suspended the first four games of the regulars season for violating the substance abuse policy, the NFL announced today.

“I apologize to my family, the Cowboys organization, my teammates and Cowboys fans for my mistake,” McClain said in a statement. “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.”

On April 1, McClain agreed with the Cowboys to a one-year, $3 million deal.

McClain played in 13 games and finished with 65 total tackles, one sack, five quarterback pressures, nine tackles for loss, two interceptions, five passes defended. He was ranked as Pro Football Focus' No. 7 inside linebacker in 2014.
