Oakland receiver Randy Moss injured his groin and bruised his ribs in a 27-14 loss to San Diego on Sunday when he crashed hard to the ground after trying to make a leaping catch.
Moss was hurt late in the first quarter when Kerry Collins underthrew him on a deep pass. Moss leaped between two defenders before falling awkwardly to the ground. Moss was attended to by trainers and limped off the field. He played only one more play the rest of the game, finishing with no catches.
He underwent X-rays, and Raiders coach Norv Turner didn't know what Moss' status would be for next week's game against Buffalo.
"He got hit pretty good, so he was in pain," Turner said.
Elsewhere, Carolina quarterback Jake Delhomme, linebacker Dan Morgan and defensive end Julius Peppers all were hurt in the Panthers' 21-20 victory against the Lions.
Delhomme was shaken up and left the game in the fourth quarter, Morgan hurt his shoulder early in the second half and Peppers injured a hand and returned later in the game. Coach John Fox said Delhomme's injury wasn't serious.
