RENTON - The Seattle Seahawks will once again have to rotate personnel along the offensive line due to injury. G J.R. Sweezy is out for Sunday's game agianst the Arizona Cardinals due to a concussion suffered last week.

While the rest of the offensive line has been in flux throughout the season, Sweezy has been the one consistent piece in the lineup. Sweezy has started all 14 games for the Seahawks this season at right guard.

Head coach Pete Carroll said the concussion happened against the New York Giants last week but they didn't realize it was an issue until later this week. Considering Sweezy was listed as having practiced on Wednesday, it was likely during that practice that symptoms developed.

"He's going through the process, the protocol, and did not make it," Carroll said.

How the Seahawks will replace Sweezy is still a question mark. Carroll wasn't very forthcoming about their plans after Friday's practice saying "

G Paul McQuistan, C Lemuel Jeanpierre, T Michael Bowie and T Alvin Bailey would be the options Seattle could turn to at the right guard position.

McQuistan has played only on the left side of the line this season at both the tackle and guard positions. He's been in a rotation at left guard with G James Carpenter the last several weeks. Seattle may want to keep that rotation going instead of moving McQuistan.

Jeanpierre is the team's only true backup center. They may not want to put him in harm's way in case an injury were to happen to starter C Max Unger so they can have a trusted snapper to turn to.

The decision could come down to Bowie or Bailey being called upon to fill the spot in Sweezy's absence. We'll have to take Carroll's advice and wait to see what they elect to do on Sunday.

CB Jeremy Lane and RB Robert Turbin were both to full speed on Friday. Lane missed Thursday's practice with an ankle injury and Turbin was limited by a sore groin. Both are listed as probable to play Sunday.

LB K.J. Wright (foot) and WR Percy Harvin (hip) are also out for Sunday's game against Arizona.
