Seahawks defensive end Chris Clemons who returned from ACL surgery three weeks ago after leading the team in sacks last year may miss Thursday’s fast-approaching game in Arizona after hyper-extending his elbow Sunday against the Titans.

“X-rays were negative; he has a sore elbow right now” head coach Pete Carroll said after Seattle’s 20-13 win over Tennessee. “Coming back on Thursday that might be hard. We’ll see what happens.”

Clemons left Sunday’s game in the fourth quarter and was taken to the locker room where trainers checked out his elbow. He never put his helmet back on.
