The Bears defense won't be at full strength in Sunday's home game against the Lions.
Cornerback Kindle Vildor has been ruled out of the contest with an ankle injury he sustained last weekend against the Dolphins. Defensive end Al-Quadin Muhammad is doubtful with a knee injury that kept him from practicing all week. And cornerback Jaylon Johnson is questionable with an oblique injury that limited him in practice Thursday and Friday.
After Vildor was injured versus Miami, he was replaced by undrafted rookie cornerback Jaylon Jones, who recorded one tackle while playing 29 snaps. The Mississippi product has appeared in nine games this season. In his only start Oct. 9 against the Vikings, he registered 10 tackles and one forced fumble in a 29-22 loss.
Other cornerbacks on the Bears roster who may see expanded playing time depending on Johnson's status are second-year pro Lamar Jackson and undrafted rookie Josh Blackwell.
With Muhammad not expected to play, defensive ends Trevis Gipson, Dominique Robinson and Kingsley Jonathan all could help pick up the slack.
Selected by the Bears in the fifth round of this year's draft out of Miami (Ohio), Robinson has played in all nine games and compiled 13 tackles, 1.5 sacks, two tackles-for-loss and two pass breakups.
"He's done really good," said coach Matt Eberflus. "We're excited where he is. He's really practiced well. He's expected to make more splash plays, more plays that are meaningful, impactful plays, more tackles, more QB pressures, and we expect that out of him going forward."
On the other side of the ball, right guard Teven Jenkins is questionable with a hip injury that limited him in practice Thursday and Friday.
For the Lions, receiver Josh Reynolds (back) has been ruled out of Sunday's game; tackle Matt Nelson (calf) is doubtful; and linebacker Malcolm Rodriquez (elbow), cornerback Chase Lucas (ankle) and safeties Kerby Joseph (concussion) and Ifeatu Melifonwu (ankle) are questionable.
A rookie third-round pick from Illinois, Joseph is the reigning NFC Defensive Player of the Week after intercepting two Aaron Rodgers passes in the Lions' 15-9 win over the Packers last Sunday in Detroit.
