Linebacker Aaron Curry practiced for a second straight day Thursday and even had an interception. The Raiders said he is doubtful to return for Sunday’s game. Curry has been on the Physically Unable to Perform list with sore knees, and the team has 21 days to clear a spot for him on the roster, put him on injured reserve or release him. Curry said he is uncomfortable talking to the media until he is closer to returning to game action. Besides cornerback Shawntae Spencer (foot) — who is now out of his boot — and tackle Khalif Barnes (groin) and tight end Richard Gordon (hamstring), running back Taiwan Jones also sat out practice with a knee injury.
