Arizona Cardinals quarterback Kyler Murray was carted off the field in the first quarter of Monday night's game against the New England Patriots after going down with a non-contact leg injury.
NFL Network's Ian Rapoport reported there is a fear that Murray suffered a serious knee injury, and the signal-caller will undergo an MRI as well as other testing.
Murray suffered the injury when he was scrambling to try to get a first down, but he fell to the turf without being tackled. After initially being deemed questionable to return, he was ruled out at the end of the first quarter.
