INDIANAPOLIS -- Patriots linebacker Rob Ninkovich injured his right knee and returned to the locker room late in the second quarter.
Ninkovich grabbed at his right knee after a 5-yard run by Indianapolis running back Donald Brown. Ninkovich was examined by trainers and walked off on his own.
But Ninkovich limped along the sideline, clutching the knee at times. He returned to the locker room at the 2-minute warning.
The Patriots said his return is questionable.
