Status report: Vance Walker questionable

ALAMEDA, Calif. -- Oakland Raiders defensive lineman Vance Walker practiced Friday for the first time since suffering a concussion at the New York Jets on Dec. 8 and is listed as being questionable to play Sunday at the San Diego Chargers.

“He’s close,” Raiders coach Dennis Allen said of Walker, who has started a career-high 13 games after starting a combined 11 in his first four NFL seasons.

“He’s still got another (concussion protocol) step that he’s got to go through, so we’ll evaluate him tomorrow. He’ll be a game-time decision.”

Also, running back Darren McFadden practiced in a full capacity after being limited the previous two days, increasing the likelihood he will play for the first time since Thanksgiving Day. He was listed as probable.

And in a minor roster move, the Raiders put rookie linebacker Sam Montgomery, who was signed to the practice squad on Wednesday, on the team’s practice squad injured reserve list with a knee issue.

“He got hurt the first day of practice,” Allen said.

“He’s a talented player, and we wanted to get him in here and take a look at him to see if he’s somebody that we could work into the future. Obviously, he had the injury, so we weren’t able to get very much of an evaluation on him.”

Following, then, is the Raiders’ status report for Sunday:

Out: RB Jeremy Stewart (ankle/knee)

Questionable: LB Miles Burris (ankle), DT Vance Walker (concussion)

Probable: TE Jeron Mastrud (wrist), Darren McFadden (knee/ankle), G Lucas Nix (illness), FS Charles Woodson (ribs), LB Sio Moore (illness)
