CHICAGO (CBS) — Barely more than a month past his frightening concussion, Bears rookie linebacker Leonard Floyd has suffered a setback with another concussion.

Floyd was carted off to the locker room in the second quarter of Chicago’s 41-21 loss to Washington on Saturday afternoon at Soldier Field after being evaluated by an independent doctor on the sidelines. He had a towel draped over his head, showing distress as he left the field.

“Man, it was tough,” teammate Pernell McPhee said of seeing Floyd leave.

Coach John Fox confirmed that Floyd had entered the concussion protocol once again, but Fox didn’t know how the injury occurred. Floyd wasn’t seen in the locker room after the game.

In November, Floyd suffered a concussion a gruesome collision with teammate Akiem Hicks. He remained down for several minutes without motion and was taken to a local hospital but later traveled home with the team. Floyd would miss the next game.

The Bears’ No. 7 pick in the 2016 draft, Floyd is second among all rookies with seven sacks on the season.

Additionally, cornerback Tracy Porter suffered a shoulder injury and is questionable to return. Rookie safety Deon Bush is doubtful to return due to an ankle injury.
