Chicago Bears quarterback Jay Cutler has been diagnosed with a sprained left ankle.

Cutler, who was making his return to the lineup after missing two games with a groin tear, exited with a little over two minutes remaining in the fourth quarter.

The 30-year-old had initial tests come back negative but ESPN reported that the team will not know the full extent of the injury until Monday.

With the Bears down by eight in the final minutes, Cutler said his injury affected his mobility and ability to pass the ball.
