Per NFL Network's Tom Pelissero, the NFL docked Hughes $53,482 for unsportsmanlike conduct relating to the incident.
Following the Bills' 21-17 loss to the Dolphins, Hughes was seen in the tunnel yelling at Ellison.
In a video of the encounter captured by Spectrum News Buffalo's Jon Scott, Hughes appears to accuse Ellison of calling him a b---h (warning: video contains profanity):
The NFL announced on Tuesday that it placed Ellison on administrative leave while while it reviews the matter. The league won't suspend Hughes.
