CHICAGO -- Despite a winning day, the Chicago Bears suffered another loss along the offensive line.
Bears coach Lovie Smith revealed after the team's 37-13 win over the Detroit Lions that left guard Chris Williams underwent emergency surgery on his wrist Sunday night. Smith didn't provide specifics about the injury and wouldn't speculate on a timetable for Williams' return.
But a source with knowledge of the situation indicated Williams suffered a dislocated wrist and would likely be out the remainder of the season.
"Injury-wise if there's a negative, something not positive about this game, Chris Williams had a wrist injury," Smith said. "He had surgery tonight. So I don't know exactly how long he'll be out, but he'll be down for a while."
The last time Smith said a player would be down "for a while," the coach was discussing starting right tackle Gabe Carimi, who hasn't been back in the lineup since suffering partial right kneecap dislocation on Sept. 18 at New Orleans.
Williams had started all nine of the team's games at left tackle this season, and the injury could further strain the Bears' depth along the offensive line.
"He('d) been playing really well as of late, so we're going to have to fill a big void there," said quarterback Jay Cutler.
Edwin Williams filled in for Chris Williams at left guard and later expressed concern about his teammate's injury.
"You never want to go into a game like that, coming in for an injured teammate," Edwin Williams said. "I just did the best I could do."
A natural guard compared to Chris Williams, who had mostly played tackle, Edwin Williams played nine games last season at guard with five starts at the position as a fill in for Lance Louis and center Roberto Garza (who was a guard at the time).
Offensive line coach Mike Tice has been high on Edwin Williams as a potential contributor in a pinch since training camp.
"We've battled from some offensive line stuff this year already," Cutler said. "Losing him is going to hurt. He was kind of one of our anchors in there helping Garza with some of his calls, some of the protections and stuff."
