After C.J. Anderson bulled in for his second touchdown of the day, the Broncos celebrated. So did the refs.

Moments after Anderson's 1-yard touchdown in the second quarter of Denver's 24-17 win over Buffalo on Sunday, line judge John Hussey and umpire Carl Paganelli fist bumped after making what turned out to be the correct call.

Bills safety Aaron Williams wasn't amused. After the game, he linked the video of the officials' reaction to a tweet that said he can't win when the referees are against his team.

The NFL had no problem with the gesture.

League spokesman Michael Signora says the two officials were acknowledging good mechanics.
