‘Caulcrick, 6-foot-0 and 260 pounds, joined the Bills’ practice squad after being released by the San Francisco 49ers on Nov. 8. The move was precipitated by injuries to the Bills’ backfield. Rookie C.J. Spiller is out for Sunday’s game at Cincinnati due to a sore hamstring. Fullback Corey McIntyre has a sore ankle and was able to practice Friday on a limited basis. McIntyre is questionable for the Bengals game.’
