Cardinals' Jake Coker: May need arthroscopic knee surgery

Coker (knee) may need arthroscopic knee surgery, Mike Jurecki of Fox Sports 910 reports.

Analysis:

Coker did not make the trip to Houston for Arizona's third preseason game as he continues to get his opinions on his sore knee. If Coker's knee does indeed require surgery, the former national champion quarterback very well could be out of a job.
