Marcus Spears won't participate in the scrimmage

OXNARD, Calif. -- It's not a surprise, but defensive end Marcus Spears said he won't be available for Sunday's Blue and White scrimmage.

Spears, who said he was tested for a concussion but doesn't have one, is being held out for precautionary reasons.

Among the missing from Sunday's walkthrough, who most likely will miss the scrimmage: Saalim Hakim (finger), Miles Austin (hamstring), Lance Dunbar (hamstring), Phillip Tanner (hand), Kevin Kowalski (foot), Bill Nagy (ankle), Nate Livings (hamstring), Mackenzy Bernadeau (knee and hip), John Phillips (ankle), Mike Jenkins (shoulder), Danny Coale (foot) and Morris Claiborne (knee).

Jay Ratliff (foot) participated in the walkthrough but isn't expected for the scrimmage. Same goes with Matt Johnson (hamstring).
