J.R. Sweezy will not play Sunday

RENTON, Wash. -- Right guard J.R. Sweezy, the only offensive lineman who had started every game this season for the Seattle Seahawks, will not play Sunday because of a concussion.

“He went through the concussion protocol and didn’t make it back,” Seattle Pete Carroll said Friday after practice.

The odd thing about Sweezy’s situation is he practiced Wednesday before the Seahawks realized he was suffering from the effects of a concussion.

Carroll said Sweezy suffered the concussion in the game against the New York Giants last weekend, but they didn’t know he had an issue until after Wednesday's practice.

Carroll would not say who will start in place of Sweezy, but the likely candidates are Paul McQuistan or rookie Michael Bowie. McQuistan has been splitting time at left guard with James Carpenter, who started the past two games.

McQuistan is an eight-year veteran who would start in his third offensive line spot this season if he plays for Sweezy Sunday. McQuistan started four games at left guard, but also played left tackle in eight games while Russell Okung was injured.

Bowie started seven games at right tackle when Breno Giacomini was out with a knee injury, but Bowie also can play guard.

The Seahawks have plenty of options. Rookie Alvin Bailey has played both guard and tackle as a sub this season. Backup center Lemuel Jeanpierre also can play the guard spot.

Everyone else is expected to play Sunday with the exception of receiver Percy Harvin, who is out after not practicing again this week.
