CHICAGO _ The Bears placed slot cornerback Bryce Callahan on injured reserve with a broken left foot Wednesday afternoon, ending his season.
Callahan broke his foot in the second quarter of Sunday's victory over the Rams. Bears coach Matt Nagy said Callahan's injury requires surgery.
The Bears signed cornerback Marcus Williams to take Callahan's roster spot. Williams is in his fifth season in the NFL. He had six interceptions for the Jets in 2015 and most recently played two games for the Buccaneers this season.
Callahan had a career-high 45 tackles and two sacks, with two interceptions and six passes defensed. The Bears brought him back this season on a one-year, right-of-first-refusal tender worth about $1.9 million. He will be a free agent this offseason.
"Bryce is extremely quick, he's very athletic," Nagy said. "He has great hands. He's tough. He's a good kid. He's very valuable. That's a big loss for us. But with that said, we're going to have a mentality it's the next man up. ... There's no sulking or none of that. It's somebody else's opportunity."
Nagy said Sherrick McManis will get the opportunity to replace Callahan in the nickel package. McManis played 56 percent of the Bears' snaps on Sunday. McManis, 30, has 19 tackles, a sack and an interception in 12 games this season.
"It's depth," Nagy said. "It's guys that understand that if they do get presented with an opportunity they have to make the most of it. That's what he's going to do. That's what he did last week. His teammates have to have his back and help him."
