NAPA, Calif. (AP) — Oakland Raiders receiver Javon Walker told the team he wanted to retire and offered to return his $11 million signing bonus before being talked out of it by owner Al Davis.

ESPN, citing an unidentified source, reported Saturday that Walker told the team on Thursday of his intentions to retire. Walker has been at practice the past two days and apparently has had a change of heart.

"That's a done issue," Walker said late Saturday following the Raiders' evening practice. " ... I'm in a great frame of mind." I'm not really sure what happened but that's a done issue. That's something that obviously people hear stuff. I'm here practicing, waiting, and (I) obviously can't wait till the season starts.

"I'm in a great frame of mind. Why wouldn't I (be)? I'm with a new team, a great bunch of guys. I'm looking forward to getting this season on the road and actually looking forward to going into next week and try to put everything together as a team and as an offense."

Walker's tenure with the Raiders got off to a rocky start after he signed a six-year, $55 million deal in March that included the $11 million signing bonus.
