Kyle Orton (right ankle) will serve as the third quarterback today after testing out his injury a while ago.
Wide receiver Brandon Lloyd will miss his fifth consecutive game with a sprained posterior cruciate ligament in his left knee. He practiced all week and was probable on the injury report. Same thing goes for linebacker Hunter Hillenmeyer, who will miss his second game following surgery on his right thumb.
UPDATED: Defensive back Danieal Manning will play after missing two games with a pulled hamstring. Nick Roach will start in place of Hillenmeyer.
For Tennessee, weak-side linebacker Keith Bulluck will extend his streak of consecutive starts to 106 games. He is playing with torn rib cartilage and will not be 100 percent. Dave Ball will start in place of Vanden Bosch. He made seven tackles and a sack in replacing Vanden Bosch last week when he left the Titans' win over Green Bay in the first quarter.
Also inactive for the Bears:
CB Marcus Hamilton
S Terrence Holt
OT Fred Miller
DT Matt Toeaina
DT Anthony Adams
For Tennessee, defensive end Kyle Vanden Bosch will sit out with a pulled groin muscle.
