All of that aside, Walker suffered an ankle injury in this past Sunday's 17-6 loss to the Panthers, which saw the Raiders unable to take advantage of four Jake Delhomme interceptions. It was a performance that ultimately led to Davis making his offensive coordinator a glorified fan for the remainder of the season.
So, how bad is Walker's injury? According to Jason Jones of the Sacramento Bee, bad enough to end his season, and perhaps, his tenure as a Raider.
"I'm done for the season," Walker said as he left the locker room on crutches and a boot on his left foot. "They've got to put some screws in." When asked if he was serious, Walker said, "yeah." Raiders interim head coach Tom Cable was unavailable for comment as Walker was seen after Cable had addressed the media. Walker was deemed "doubtful" for Sunday's game in Miami by Cable on Wednesday.Walker has played in only 33 of a possible 64 games over the past four seasons, and has never really come close to matching the production he put up during the 2004 season as a member of the Green Bay Packers.
