Per a report from AL.com, former Alabama and current San Diego Chargers defensive tackle Damion Square has been suspended four games by the NFL for violating the league’s Policy and Program for Substances of Abuse.

The 6-foot-2, 293-pound Houston native will be eligible to play in Week 5 of the regular season. During this preseason, he led the team with two sacks, and also accrued three tackles-for-loss.

Square was remorseful over the announcement, and issued this statement:

“I sincerely apologize to my teammates, coaches, the entire Chargers organization as well as the fans. I made a mistake and take full responsibility. I look forward to returning in Week 5 and doing whatever I can do to help the team.”

Square became the third former Alabama player recently to suffer a suspension at the hands of the NFL. Dallas Cowboys linebacker Rolando McClain was given a 10-game suspension, and Buffalo Bills defensive lineman Marcell Dareus was handed a four-game suspension last week.
