Seahawks place James Carpenter on the reserve/non-football illness list

Seattle Seahawks offensive lineman James Carpenter is done for the season after he was placed on the reserve/non-football illness list, the team announced on Tuesday.

The Seahawks promoted Rishaw Johnson from the practice squad to take Carpenter's roster spot.

Carpenter left the game on Sunday with pain in his surgically repaired left knee. As Danny O' Neill of the Seattle Times points out, the Seahawks haven't said what the non-football illness is.

He had ACL surgery on his left knee last December and made a quick recovery to start five games this season. He suffered a concussion in a 28-24 loss against the Detroit Lions on Oct. 28 and missed the following games against the Minnesota Vikings and New York Jets.

Seahawks head coach Pete Carroll told the News Tribune that he expects Carpenter back eventually, and commended Carpenter's rehab regimen:

"He's shown us enough at this time that we know what he's capable of doing. We're excited about his future and all. If we can't get him back right away, we still have gained some. It was a major and miraculous recovery that he made, and he's to be complimented for that."

In the meantime, Carroll expects to use John Moffitt and J.R. Sweezy on occasions to fill Carpenter's hole at left guard.
