Seahawks linebacker Bobby Wagner came into Sunday's game having played every defensive snap this season, compiling a league-leading and franchise record 170 tackles on his way to an eighth consecutive Pro-Bowl selection. 

Against the Lions, however, Wagner saw that streak come to an end early in the game when he slipped on Detroit's first play from scrimmage, coming down awkwardly doing the splits and suffering what Seahawks coach Pete Carroll said is a knee sprain, the result of which will not be known until an MRI can be performed. 

"Bobby sprained his knee," Carroll said. "He's got an MRI coming up this evening. Initially it didn't look obviously really bad, but we don't know that. We've got to wait and see."

Wagner was able to walk off the field under his own power and actually tried to return to the game after a TV timeout, but because he had received medical attention on the field, he had to come out for a play. That extra time to assess the situation led to the Seahawks deciding to keep Wagner out of the game, with Cody Barton taking over at middle linebacker.  

"I don't know that," Carroll said when asked about Wagner's availability for Seattle's season finale against Arizona. "We've got to get through tonight… He sorted it out, came running off like the stud that he is, he ran back in. I'm really glad that we took care of him and kept him out."

Carroll added that while Wagner briefly tried to return to the game, he and the team, "just felt like it was better to not go, make sure we know what's going on with it instead of just going back on again."

The Seahawks had a few other players leave the game with injuries, including running back DeeJay Dallas, who has what Carroll described as a thigh bruise; Carlos Dunlap II, who injured his ankle; cornerback John Reid, who was evaluated for a concussion; and tight end Will Dissly, who has a heel injury.  

"He banged his heel," Carroll said of Dissly. "He's got a heel bruise or something. I'm not sure what it is right now."
