CHICAGO — Detroit Lions rookie quarterback Matthew Stafford had his right knee wrapped after he twisted it during the fourth quarter of Sunday's game against the Chicago Bears.

The Lions had a third down at the Bears 6 when Stafford twisted his leg as he was sacked for an 11-yard loss by Adewale Ogunleye.

That forced Detroit to kick a field goal, which cut Chicago's lead to 34-24 with 8:15 left. Daunte Culpepper replaced Stafford on the Lions' next possession.
