LAKE FOREST, Ill. -- Bears coach Lovie Smith confirmed on Monday that starting left guard Chris Williams is being placed on injured reserve with a dislocated left wrist which required immediate surgery following halftime of Chicago's home victory over the Detroit Lions.
"Chris Williams has been playing good football, but with that wrist injury we'll put him on injured reserve and he'll miss the rest of the season, which is a tough break for us and a tough break for Chris," Smith said.
"It's very similar to what (Bears middle linebacker Brian Urlacher) went through (in Week 1 of the 2009 regular season)," Smith said. "It's unfortunate. Chris is a tough guy, made it through the half ... you could tell something was wrong but we didn't know it was that. Again, he'll be back in time."
Urlacher, appearing Monday on "The Waddle & Silvy Show" on ESPN 1000, lamented Williams' loss.
"We lost a big one," Urlacher said. "We lost Chris. That's really going to hurt us. He was playing well this year.
"I think it's the same thing I did to my wrist a couple of years ago. It's too bad he'll be out, but somebody will step in."
Third-year guard/center Edwin Williams replaced Chris Williams at left guard in the second half against the Lions.
"Edwin came in a did a good job for us. Edwin has started for us around here, knows what we do and there's a reason why he's on the roster," Smith said. "We feel good, need a backup to step up with Edwin stepping in if that's (what) duty calls."
After playing in four regular-season games, including two starts, for the Washington Redskins in 2009, Edwin Williams found his way onto the Bears practice squad at the onset of 2010. A few weeks into the season the Bears signed Williams to the active roster where he made three starts at right guard.
Williams entered this past training camp as a candidate to replace Olin Kreutz at center, but started the year as the eighth and final offensive lineman on the roster. But due to a variety of injuries on the offensive line, Williams has been active on game day in eight of the first nine weeks of the regular season.
In the event the Bears decide to go in a different direction, veteran Frank Omiyale did start 12 games at left guard in 2009, plus a pair of games at right guard in 2010, before moving outside to tackle.
Starting right tackle Gabe Carimi underwent arthroscopic knee surgery last week. If he is able to return, the Bears would also have the option of starting him and moving current starting right tackle Lance Louis back to guard, where he played when the season began.
Smith refused to completely commit to Williams as the new left guard, although the odds seem favorable.
"We don't usually talk about who is going to start this early in the week, but if Edwin ends up being the starter there, we'll be pretty excited about that," Smith said.
The Bears also waived defensive end Nick Reed on Monday and signed former Atlanta Falcons defensive end Chauncey Davis. Davis had 25 starts for the Falcons from 2005-10 and was a fourth-round draft pick in 2005.
