After Broncos running back C.J. Anderson scored a one-yard touchdown in the second quarter, line judge John Hussey and umpire Carl Paganelli fist bumped upon agreeing it was a touchdown. On Sunday night, Williams tweeted that the Bills couldn't win if they were also competing against the officials.
On Monday, Williams stood by his comments that the officials were in the wrong.
"I don't care if I do get fined," Williams told the Associated Press on Monday. "I speak the way I feel, and that's the way I feel."
League spokesman Michael Signora said the officials made the gesture to congratulate each other on making the right call.
Despite two fourth-quarter touchdowns by Kyle Orton, the Broncos won the game 24-17 as the Bills' rally ran out of time.
