LeSean McCoy tore his MCL and will be "week-to-week" pending further evaluation.
Rex Ryan said Monday that McCoy will have an MRI to determine the full extent of the injury, but calling McCoy week-to-week at this point in the year could make it likely that we’ve seen the last of the back this year.
If his year is over, McCoy will finish his first season with the Bills with 203 carries for 895 yards and three touchdowns in 12 games.
