The Seahawks had only one player leave Sunday's win in Detroit with an injury, which is good news for the team, but the unfortunate part is that the foot injury that knocked outside linebacker Darryl Johnson out of the game is a significant one that will keep him out for some time, Seahawks coach Pete Carroll said. 

Johnson, who the Seahawks claimed off waivers last month, first started seeing playing time on defense when Shelby Harris went down with an injury in Week 2, and he continued to impress his coaches to the point that he earned the start in Sunday's game.

Carroll said the injury should not keep Johnson out for the seasons, but it sounds like he will miss some time. 

"He hurt his foot," Carroll said. "He's got an injury that's going to take a while. I don't know specifically, but I do think it's a stress-fracture type of thing that he's dealing with, so that's somewhat of a significant injury.

"I was really fired up about him being part of our plans. He's big, strong, versatile, active, smart, really one of our guys, so I'm really disappointed he got banged up. He was the one really that got hurt in this game." 

This week could mark the return of defensive end L.J. Collier, who went on injured reserve in Week 1 with an elbow injury. 

"There's a chance L.J. comes back this week, that'd be good for us to get him back in the action and see where he goes," Carroll said.
