LeSean McCoy, the running for the Philadelphia Eagles, limped to the locker room on Thursday night against the Kansas City Chiefs.
McCoy was down for a moment on the field and took off his helmet in the second quarter as trainers tended to him before he got off the field under his own power.
NFL.com reported that he is getting X-Rays on his right leg.
He rushed six times for 14 yards.
McCoy, 25, last year rushed for 840 yards and two touchdowns.
