LAKE FOREST, Ill. — Bears slot cornerback C.J. Gardner-Johnson suffered a concussion during a Week 18 loss to the Detroit Lions. The veteran was down on the field for a while, and then skipped the sideline injury tent and headed straight for the home locker room.

He hasn’t been on a football field since.

Gardner-Johnson missed the entire practice week leading up to Saturday’s NFC wild-card round playoff game against the Green Bay Packers, so it was no shock to see him ruled out on the official Bears injury report.

The Bears are fortunate to have a reinforcement working his way back to action. Kyler Gordon was designated to return from his second injured reserve stint Monday, and he worked through each part of the practice week. He was formally listed as questionable — standard procedure for players who’ve been on IR even when the plan is to activate them before kickoff.

Defensive coordinator Dennis Allen said Gordon is part of the Saturday game plan, though the Bears needed to see how he would respond to practice activity. He dealt with a hamstring injury earlier in the season, but a groin issue has sidelined him lately. He returned in Week 13 from the hamstring problem but was ruled out during pregame warmups before the Week 14 contest at Green Bay.

Offensive lineman Braxton Jones, also designated to return from IR, is questionable, too.

Wide receiver Rome Odunze will return after five games missed with a foot injury. He did not receive an injury designation. Neither did receiver DJ Moore (knee) nor offensive tackle Ozzy Trapilo (quad), both of whom were limited this week.

In other injury news, linebacker Amen Ogbongbemiga (concussion) and defensive end Joe Tryon-Shoyinka (concussion) also were ruled out.
