LAKE FOREST, Ill. (AP) — The Chicago Bears returned to work Monday after their bye week elated to have several missing pieces back but without key players from their front line on both sides of the ball.

Right guard Kyle Long went on season-ending injured reserve because of a hip injury, and coach Matt Nagy said defensive end Akiem Hicks would miss time due to an elbow injury suffered Oct. 6 against the Oakland Raiders.

“They’re huge parts of the team in more ways than just personalities,” Nagy said. “They’re some big dudes, now. You look at those two guys going against each other in training camp, they’re massive individuals.

“But it is what it is. We love those guys, and we appreciate them, but we can’t look back. We’ve got to go. I’m not going to let anybody sit here and sulk about what-if or anything. That’s where we’re at. There are all these other teams that are having a bunch of different injuries and situations that go on.”

Positives on injuries involved the passing game, with quarterback Mitchell Trubisky throwing at Monday’s practice for the first time since he suffered a left shoulder injury three weeks ago.

Trubisky hasn’t been confirmed as a starter this weekend against New Orleans.
