With Lance Louis (knee) and Devin Hester (concussion) already ruled out with injuries, running back Matt Forte suffered an ankle injury in the third quarter against the Minnesota Vikings.
Officially, Forte was listed as questionable. But when the fourth quarter started, Forte was not on the Bears' sideline.
Forte was hurt on a three-yard run at 6:39 in the third quarter. He fumbled the ball on the play and Vikings safety Mistral Raymond returned it 52 yards for a touchdown. But the play was reviewed and overturned as replays showed Forte's knee was down.
Forte had 14 carries for 42 yards against the Vikings before being listed as questionable. Veteran Michael Bush had two short touchdowns runs prior to Forte's injury, but received more carries with Forte out. Third-string running back Armando Allen also played for the Bears.
