Carson Palmer is active

OAKLAND -- Oakland quarterback Carson Palmer is active. The Raiders have not announced who will start.

Palmer has been on the field warning up since shortly after 1 p.m. ET. ESPN’s Colleen Dominquez has reported that the decision if Palmer plays will be up to him. The Oakland coaching staff is going to let Palmer decide if he is comfortable enough physically and emotionally to play. He hasn’t played since Jan. 2. Oakland gave up a first-round pick in 2012 and a conditional first-round pick in 2013 to Cincinnati for Palmer on Tuesday, two days after starter Jason Campbell broke his collarbone.

If Palmer doesn’t play Sunday, Kyle Boller will start. Rookie quarterback Terrelle Pryor is active for the first time this season.

Meanwhile, Oakland kicker Sebastian Janikowski is inactive with a hamstring injury. Oakland signed Dave Rayner to kick.

Oakland linebacker Rolando McClain is active after missing all week of practice with a foot injury.

Kansas City rookie receiver Jonathan Baldwin is expected to make his debut Sunday.

Campbell is on the Oakland sideline. He had surgery Monday.
