Nick Roach's injury 'nothing major'

DETROIT -- After undergoing x-rays and preliminary testing from team medical personnel, Bears linebacker Nick Roach said the hip injury he sustained Sunday in the team's 24-20 win over the Detroit Lions isn't serious.

"Everything is good," Roach said as he walked out of the locker room without displaying any noticeable effects from the injury. "This is nothing major."

Starting in place of the injured Pisa Tinoisamoa (knee), Roach left Sunday's game early in the second quarter because of the injury. After halftime, the Bears announced Roach wouldn't be able to return. He was replaced at strongside linebacker with Rod Wilson, who finished the game with three tackles.

The club also operated out of a nickel package for a significant portion of the second quarter.

"It says a lot a guy like Rod Wilson that he stepped in -- he's the backup [middle linebacker] -- but he stepped in and did a pretty good job," Bears coach Lovie Smith said. "Nick went down and couldn't finish the game."

Roach said his injury was confined to "the muscle" in his hip, which would seem to indicate a strain of some sort. But the linebacker wouldn't elaborate on any of the specifics regarding the injury.

Roach's latest setback casts concern on the future availability of the club's top two strongside linebackers. Plagued by recurring issues in his right knee, Tinoisamoa missed his second game this season on Sunday, which made it possible for Roach to start. It's unclear whether Roach or Tinoisamoa will be available for next week's game against the Patriots. The Bears aren't likely to provide an update on either players' conditions until Wednesday.

While it's unlikely that both Roach and Tinoisamoa will miss next week's game, the club's other two options at the position appear to be Wilson and Brian Iwuh, who started a game on the weak side on Oct. 17 in place of Lance Briggs.
