Chicago Bears quarterback Jay Cutler has reportedly been ruled out for at least two weeks due to a hamstring injury.
The 32-year-old sustained the injury in the second quarter of his side's defeat to the Arizona Cardinals when he attempted to chase Tony Jefferson following an interception.
Cutler was ruled out for the rest of the match and was replaced by Jimmy Clausen, who struggled in his time on the field, throwing for 121 yards and an interception.
ESPN have reported that Cutler will face at least two weeks out of action to recover from the hamstring injury, leaving Clausen as the Bears' starter for their next two matches.
John Fox's men are 0-2 in their season following their loss to the Cardinals.
