The Chicago Bears have been able to stay relatively healthy here in 2018 following numerous years filled with injury woes. In the team's win on Sunday against the Los Angeles Rams, nickelback Bryce Callahan was forced to leave the game with an injury. Head coach Matt Nagy offered very little about the injury after the game and on Monday, only stating the Bears were still evaluating the young defensive back.

Mike Garafolo of the NFL Network cleared up some of the specifics of the injury on Twitter on Tuesday.

"Bears nickel CB Bryce Callahan suffered a broken bone in his foot in Sunday's win over the Rams, sources say," Garafolo tweeted. "Fifth metatarsal. His timeline is TBD but he'll likely be out a while. He was balling, so a tough one for Chicago."

The news first started circulating about the injury after a memorabilia shop in Chicago noted Callahan was going to be unable to attend a signing on Tuesday night because he broke his foot.

Callahan has been an impressive part of Chicago's defense this season at the nickelback spot. In 13 games this year, Callahan has recorded 45 tackles, two sacks, six pass deflections and two interceptions. He has made a major impact at the position this year and has largely flown under the radar with his play.

Signed as an undrafted free agent out of Rice in 2015 by the Bears, Callahan has gotten better each year in Chicago. He impressed defensive backs coach Ed Donatell and coordinator Vic Fangio enough to earn nine appearances with three starts in his rookie season. In those nine games he recorded 21 tackles, one sack and four pass deflections. The following year he saw his role increase on defense. He appeared in 11 games with 10 starts, racking up 32 tackles and five pass deflections while splitting time out of the slot and on the outside.

Last season he also struggled with injuries, appearing in 12 games with six starts. He went on to record 25 tackles, one sack, six pass deflections, one forced fumble and two interceptions. He also returned one punt for a 59-yard touchdown on a trick play against the Minnesota Vikings to cap off the 2017 season. Callahan entered the offseason as a restricted free agent and was given the original-round tender by the Bears. He did visit the Vikings during the offseason but eventually signed his tender from Chicago.

Sherrick McManis is the most likely option to replace Callahan at the position. McManis is the longest-tenured Bear on the roster. He first joined the team via trade with the Houston Texans back in 2012 for fullback Tyler Clutts, meaning he has played under Lovie Smith, Marc Trestman, John Fox and Matt Nagy.

McManis saw the majority of his action on defense back in 2015 when he recorded 29 tackles. He has been used primarily on special teams in his career. He entered Sunday night's game with 12 tackles, one sack, one pass deflection and one interception. He finished the contest with a team-high seven tackles. He also played a season-high 35 snaps on defense.

Nagy will meet with the media on Wednesday ahead of practice and should be able to provide more updates on the injury.
