San Francisco 49ers defensive lineman Demarcus Dobbs has been suspended without pay for the first game of the 2013 regular season for violating the NFL Policy and Program for Substances of Abuse.
He was arrested in December on a misdemeanor possession of marijuana charger.
Dobbs, who finished last season on injured reserve with a knee injury, will be eligible to return to the active roster the day after the team's Sept. 8 opener against the Green Bay Packers. He is eligible to participate in all offseason and preseason practices and games.
Dobbs was the only player on the team who played on every special teams unit last season while also being a part of the defensive line rotation and even seeing some snaps at tight end in special packages.
"I appreciate all the support that I've had from my friends, my family and my fans," Dobbs said following the arrest. "It's very out of character for what happened. I made a dumb mistake, a dumb decision. I take full responsibility for it. Going forward, I can guarantee it won't happen again. It's not like me. I never had any problems before at all. It's just a dumb decision that I take full responsibility for."
