RENTON – Center Max Unger left Sunday's game after the third quarter with an injury to his pectoral muscle. When Unger will be able to return is very much up in the air, and probably will stay that way all the way through this week, according to coach Pete Carroll.
"We've just got to see how he responds during the week," Carroll told 710 ESPN Seattle's "Brock and Danny" on Monday. "It's something that one of our guys has had before and played with it. So we'll find out how it is particularly for him."
That's very likely a reference to quarterback Tarvaris Jackson, who played the second half of the 2011 season after suffering a severe strain to the pectoral muscle in his throwing arm.
Now, there are clear differences, the first being Jackson is a quarterback whose job is to throw a football while Unger is a lineman expected to block opponents who are the approximate size of a refrigerator.
It's a situation that bears watching, though. A completely torn pectoral muscle is generally a season-ending injury that requires surgery, and that's the injury that ended Russell Okung's 2011 season.
Unger missed three games earlier this season, two because of a triceps injury and then sat out the Nov. 10 game at Atlanta because of a concussion.
Lemuel Jeanpierre is Seattle's backup center.
