Baltimore Ravens running back Ray Rice left Sunday's game against the Cleveland Browns early in the fourth quarter with a hip flexor strain.
Rice wasn't touched before going down near the line of scrimmage on a run to the right side. He grabbed his left hip as he fell.
Ravens coach John Harbaugh said Rice wasn't scheduled for an MRI.
Rice had 13 carries for 36 yards and a fumble before leaving. The Ravens scored a touchdown on the drive after he went down and won the game 14-6.
