Buffalo Bills defensive end Jerry Hughes was fined $53,482 for unsportsmanlike conduct on Saturday in the wake of his confrontation with umpire Roy Ellison following last Sunday's game against the Miami Dolphins.
Hughes was shown on video yelling at an official in the tunnel of Miami's Hard Rock Stadium after Buffalo's 21-17 loss.
The video showed Hughes accusing the official of calling him a b--. He continued to shout at the official while being restrained by a Buffalo staffer and Bills offensive lineman John Miller yelling "I'll catch you" before adding: "Guarantee it! Gonna knock his (expletive) out when I see him on the streets."
Inside the locker room, Hughes denied the confrontation took place while speaking to reporters. He said he did not recall whether the official called him a "b--- during the game.
"I lost the game so I'm supposed to be angry," Hughes said. "We just played our butts off for four quarters and we came six inches short of winning the football game. So I think myself, with a lot of Buffalo Bills fans, are probably upset right now. That's just the nature of sports. Someone is going to win and someone is going to lose."
Ellison was placed on administrative leave on Tuesday but ESPN reported he is not expected to be suspended.
Ellison, who is in his 16th season as an NFL official, was previously suspended one game without pay in 2013 for making profanity and derogatory statement to Washington Redskins offensive lineman Trent Williams in a game against the Philadelphia Eagles.
