Carr hasn’t been ruled out

Raiders quarterback Derek Carr participated in Friday’s practice and was listed as questionable for Sunday.

“We have time before we tee it up,” head coach Jack Del Rio said in reference to all five Raiders listed as questionable. “They’ll remain a question mark until we make the final decision.”

Carr must be making quick progress from his transverse process fracture in his back.

Monday, Del Rio said the quarterback would miss two to six weeks, meaning he’d be unavailable Sunday. Thursday, tackle Donald Penn said Carr was “ahead of schedule.”

Friday, Carr was seen throwing passes toward the end of practice and wasn’t being ruled out for Sunday.

“I’m not going to really talk about injuries,” Del Rio said, “and what we may and may not do or who we may or may not play or when and all that kind of stuff, when we’re going to utilize people.”

Asked if Carr has been pushing to play Sunday, Del Rio said, “Yeah. That’s what all competitors — you would hope they would do.”

Carr was hurt in the third quarter of Sunday’s loss in Denver, which dropped the Raiders to 2-2. EJ Manuel is expected to start against the Ravens. Briefly: The other four players questionable are cornerback David Amerson (consussion), cornerback Gareon Conley (shin), right guard Gabe Jackson (foot) and running back DeAndre Washington (hamstring). Like Carr, all were limited in Friday’s practice. Amerson cleared the league’s concussion protocal, Del Rio said . ... Wide receiver Michael Crabtree will play Sunday after missing last week’s game with a chest injury.
