OXNARD, Calif. -- Morris Claiborne missed Wednesday's practice with some stiffness in his left knee. Claiborne was held out as a precaution but it's questionable if he plays in the second preseason game at Oakland on Friday night.
The Cowboys' trainers wanted to see if Claiborne could practice on Wednesday after jamming the knee Tuesday afternoon.
"It's a little tight, a little stiffness," said Claiborne, who suited up but didn't practice. "I would be real disappointed (if I didn't play). I'm really looking forward to this game, really looking forward to being out there with my teammates. I know this will probably be the first game where everybody that probably gets a chance to take some snaps. Just being out there with those guys in this first game, I was really looking forward to it."
The Cowboys have a walkthrough practice Thursday morning before flying to Oakland and there's a chance he could participate.
Also, Kevin Kowalski (knee), Ryan Cook (back) Ray Dominguez (shoulder), Jeff Olson (concussion), Nate Livings (knee), Demetress Bell (conditioning), Jermey Parnell (hamstring), Terrance Williams (concussion), Matt Johnson (foot), Brandon Carr (personal), Alex Albright (back), Jay Ratliff (hamstring) and Anthony Spencer (knee) missed practice.
Carr should return Thursday for the walkthrough practice but Cook suffered a setback because he just returned to practice on Tuesday. Cowboys executive vice president Stephen Jones said Ratliff and Parnell are progressing in their rehabs. Albright said he's hopeful to return for the Raiders game.
