LAKE FOREST, Ill. -- The Chicago Bears conducted a full practice session Thursday with a few players who missed Wednesday's workout returning to the field, including running back Matt Forte (ankle), who "looked pretty good," according to coach Lovie Smith.
Smith called Allen's situation "a concern" because the coach "assumed he would be able to go today, but he wasn't."
While Urlacher has gradually improved, it's still uncertain whether he'll play Sunday when the Bears face the Detroit Lions at Ford Field. Conte, meanwhile, isn't expected to play.
Regarding Forte, Smith said, "We're hopeful for him, which we thought all along. He's been pretty optimistic about the plan."
As for Melton, who missed Sunday's game against the Arizona Cardinals, Smith said that "if a guy practices on a limited basis, that's a good thing. Every pass rusher we have on our team against a group like this, we'll need them. Hopefully he'll be OK (to play Sunday)."
The Bears also listed cornerback Tim Jennings (shoulder) on the injury report with offensive tackle Jonathon Scottt (hamstring). Both participated fully in Thursday's practice session.
For the Lions, safety Louis Delmas (knee) was held out of practice, along defensive tackle Sammie Hill (toe), and tight end Brandon Pettigrew (ankle). Receiver Calvin Johnson (knee/ankle) returned to the field Thursday and participated on a limited basis as did cornerback Chris Houston (hamstring).
The Lions listed cornerback Don Carey (knee) as a full participant.
