ORCHARD PARK, N.Y. -- Buffalo Bills safety Aaron Williams told The Associated Press that he isn't backing away from his criticism of NFL officials and doesn't care if he's disciplined.

"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."

Williams took issue with a fist bump between two officials after Denver running back C.J. Anderson scored his second of three touchdowns in the Broncos' 24-17 win on Sunday.

After the game, Williams expressed his displeasure on Twitter by accusing the officials of teaming up with the Broncos.

No excuse for my performance but can't win playing 16 vs 11 thought I seen it all Smh https://t.co/CrfVO2YxA6 — Aaron Williams (@ajwilliams23) December 8, 2014

Williams was referring to the number of on-field officials, although there are actually seven and not five at NFL games.

The league had no problem with the gesture , which came after line judge John Hussey and umpire Carl Paganelli consulted to determine whether Anderson had crossed the goal line before his knee was down.

"It was an acknowledgement of good mechanics between the two officials involved in making the call," NFL spokesman Michael Signora said.

The loss was costly for the Bills (7-6), who fell to the fringes of a tightly jumbled AFC playoff picture. As a result of tiebreaking formulas, Buffalo ranks 11th in the standings with three games left.

The Bills host Green Bay on Sunday.

Williams wasn't the only Bills player to complain about the officiating or the fist bump immediately after the game and on Monday.

Cornerback Corey Graham took a more diplomatic approach by saying the officials' celebration wasn't a "good look," but he understood what prompted it.

"I saw it. I don't think it was nothing crazy as far as 'Happy that they scored a touchdown,'" Graham said Monday. "It was more of probably just, 'We got that one right.'"
