OXNARD, Calif. -- Cowboys cornerback Morris Claiborne missed another day of practice with a sore left knee.
Claiborne suffered the injury last week and hoped to play in the second preseason game. His status for Saturday's preseason game at Arizona is in question.
"I believe anything is a setback," Claiborne said after Monday's practice. "This is a big setback. It might not be to somebody else, but it is to me. I have big goals for myself."
Claiborne said he hasn't undergone an MRI or X-ray because there is nothing structurally wrong with the knee.
"At this point, I'm just following directions, just going through the treatments," Claiborne said. "I thought I would be ready the next day, and, obviously, I wasn't."
Also, cornerback B.W. Webb sprained his right ankle and missed the team drills. J.J. Wilcox (personal matter), Matt Johnson (foot), Eric Frampton (hamstring), Alex Albright (back), Ernie Sims (groin), Jay Ratliff (hamstring), Anthony Spencer (knee), Sean Lissemore (groin), Cole Beasley (foot), James Nelson (ankle), Ryan Cook (back), Ray Dominguez (shoulder), Kevin Kowalski (knee), Nate Livings (knee) and Darrion Weems (sore chest) didn't practice.
