FLAGSTAFF, Ariz. (AP) -Arizona Cardinals outside linebacker Chike Okeafor will probably miss the season after undergoing surgery Tuesday to reattach a torn biceps tendon.

Okeafor was holding out hope for a return this season, coach Ken Whisenhunt said, but the normal recovery period for that type of surgery is four months.

Darryl Blackstock and Calvin Pace are competing to replace Okeafor in the starting lineup.

Right tackle Oliver Ross, meanwhile, was getting a second opinion about his torn triceps tendon. That injury also could require season-ending surgery. First-round draft pick Levi Brown has moved into Ross' spot.

Okeafor and Ross were injured in last weekend's preseason opener at Oakland.

Whisenhunt said center Nick Leckey will miss Saturday's preseason game against Houston because of a sprained knee.

The Cardinals signed two free agents - guard Brad Badger and center Scott Peters - to bolster their dwindling depth on the offensive line. Badger has played 10 NFL seasons. He appeared in nine games last year for Oakland. Peters, who played at Arizona State, spent last season on injured reserve with Carolina because of a foot injury.

Arizona also released fullback BranDon Snow, a rookie free agent out of Penn State.Copyright © 2005 The Associated Press. All rights reserved.
