‘The Bills activated Cary Harris off the practice squad Friday to be the fourth cornerback. Harris was activated because linebacker Keith Ellison was placed on injured reserve due to a quadriceps injury. Also listed as questionable were Kyle Williams (knee), Jairus Byrd (groin) and James Hardy (groin). All practiced to some degree Friday. Williams and Byrd seem like they have a decent chance to play. Also listed as out is Demetrius Bell (knee).’
