Rex Ryan says Bills had to "back out" LeSean McCoy from practice today after he experienced tightness in his hamstring.
Fantasy Impact:
He wasn't on the Wednesday injury report so this is one of those dreaded midweek downgrades. Karlos Williams figures to get most of the carries if McCoy can't play, but Anthony Dixon is a threat to vulture goal line carries. The Patriots were gashed on the ground by DeAngelo Williams, so there's some upside here.
