Bills LB Terrel Bernard left in the fourth quarter of Sunday's win over the Titans with a right ankle injury. The team ruled him out for the rest of the game. Bernard returned to the sideline still in full uniform before the end of the game. And Buffalo had the game well in hand, leading by 14 at the start of the quarter. HC Sean McDermott said after the game we'd learn more about Bernard's injury Monday. Baylon Spector would fill in if Bernard misses time.
