The Chicago Bears will likely be without starting center Will Montgomery, who will be out for a while after breaking his fibula in Sunday's win over the Raiders.
"Will Montgomery left the game today and did not return with a left leg [injury]," head coach John Fox said. "Early calls on that are that it is a broken fibula."
The injury occured on the third snap of the game, when left tackle Charles Leno rolled up on Montgomery's left leg. Recovery time for a broken fibula, a bone located in the shin, is roughly six weeks, although the severity of the injury is still unknown.
"As far as a timetable, I don't know yet," Fox said.
Matt Slauson replaced Montgomery, moving from left guard to center.
"That's not what you want to see. I don't want to see it," Slauson said. "Will was my guy. He's a great player for us. He's what sets the whole offense."
Safety Antrel Rolle left the game in the third quarter with an ankle injury. He said after the game the injury is not as bad as he initially feared.
"Thank God nothing is broken," Rolle said. "It could have been a lot worse than it is."
It's unclear how long Rolle will be out.
