Jeffery reportedly has stayed in shape, so he should be good to go after a week of practice.
"I just know what he's doing, and you have to first off, stay in the game mentally, and he's doing that," Bears coach Lovie Smith said. "He's doing all the things you can do if you're injured, and to be a good pro for years to come.
"You're going to have an injury, you're going to have to deal with it, so you're going to have to learn this routine, which he's doing. No complaints about him at all, can't wait to get him back out there."
