Derek Carr: Raiders are different than they were three weeks ago

CLEVELAND -- Observed and heard in the locker room after the Oakland Raiders' 23-13 loss to the Cleveland Browns:

Carr says Raiders are different now: Oakland rookie quarterback Derek Carr said the team is different in the past three games under interim coach Tony Sparano than they were under fired coach Dennis Allen, who was let go after Week 4. Carr said he doesn't know why, because the team believed in Allen, but he said he is excited about the immediate future.

Injury update: Cornerbacks Chimdi Chekwa (hamstring) and TJ Carrie (back) and right tackle Menelik Watson (stinger) were hurt during the Raiders' loss Sunday. Sparano didn’t know the severity of any of the injuries.

Sparano stands by fake field goal: Backup quarterback Matt Schaub threw an interception on a fake field goal (the snap was botched) on the first drive of the game. The Browns turned it into a field goal. Sparano said he was trying to win on the road.

Woodson says it comes down to execution, not effort: Oakland leader Charles Woodson said effort is not the problem; it's execution. He said that has to be the focus.
