LeSean McCoy suffered an ankle injury late in the Chiefs' 28-10 win over the Raiders on Sunday and he will undergo an MRI on Monday to evaluate the severity of the injury, Ian Rapoport of NFL.com reports.
McCoy's injury is not expected to be major, but nothing is certain yet.
Through two games, he leads Kansas City with 104 rushing yards on 21 carries.
The Chiefs signed the two-time All-Pro late in training camp after he was cut by the Bills. McCoy previously played with Chiefs coach Andy Reid when he started his career with the Eagles.
