The Seattle Seahawks announced today that offensive guard James Carpenter has been ruled out of Sunday’s game against Minnesota due to a concussion.
Carpenter was a surprise addition to Friday’s injury report. He was listed as questionable with an illness, and was a limited participant in practice.
Carpenter started five games at left guard this season, coming off ACL knee surgery that cut short his 2011 season. Paul McQuistan started the first three games at left guard before sliding over to right guard to make room for Carpenter when he returned to the starting lineup.
The Seahawks could move McQuistan back to left guard again and replace him at right guard with John Moffitt.
Or the Seahawks could decide to let McQuistan stay put, and either start Moffitt or rookie J.R. Sweezy at left guard, which would be less of a shake-up to the starting five.
Whatever decision offensive line coach Tom Cable makes, Seattle likely will be starting its fifth different starting offensive line combination on Sunday.
