The NFL has placed official Roy Ellison on administrative leave while it investigates an accusation that he called Buffalo Bills defensive end Jerry Hughes a vulgar name during Sunday's game in Miami. Hughes confronted Ellison in the tunnel near the locker room after Buffalo's 21-17 loss. The video shows him accusing the referee of using the derogatory term. Ellison was suspended in 2013 for making a derogatory statement to Washington tackle Trent Williams during a game. Bills coach Sean McDermott on Monday said he was leaving the matter in the league's hands after saying he's spoken to both the NFL and Hughes.
