Kansas City Chiefs running back LeSean McCoy injured his ankle in Sunday's win over the Oakland Raiders and will undergo an MRI to determine the severity, per Ian Rapoport of NFL Network.
Rapoport noted "it doesn't appear to be major, but the MRI will tell all."
The Chiefs took a flier on McCoy following his surprise release by the Buffalo Bills on Aug. 31. He reunited with head coach Andy Reid, who originally drafted him in 2009 with the Philadelphia Eagles.
Through two games, McCoy has 21 carries for 104 yards and no touchdowns.
