Oakland Raider center Barret Robbins spent 30 days in a treatment facility for a mental disorder and alcohol abuse.
The All-Pro lineman disappeared the night before the Raiders' 48-21 Super Bowl loss to Tampa Bay in San Diego on Jan. 26.
A statement released Wednesday by his agent, Drew Pittman, was the first official disclosure of Robbins' treatment.
"I love the game of football and while it is going to be hard to face my teammates and the public, it is something I have to do," Robbins said in the statement.
"I will continue to receive ongoing treatment and will remain on medication to treat my bipolar disorder. I understand my sincerity will be judged by my actions, not my words."
Robbins missed two meetings and a walkthrough the day before the game, and Raider Coach Bill Callahan said Robbins was incoherent when he showed up late that night.
Robbins, who has a history of depression, was treated at an undisclosed facility.
Raider senior assistant Bruce Allen said the team hasn't ruled out the possibility of Robbins playing for them in the 2003 season.
