ORCHARD PARK, N.Y. (AP) - Three Buffalo Bills defensive backs are paying a price for their involvement in a pre-game, on-field altercation with members of the New England Patriots last weekend.

Safety Robert Blanton says the NFL fined him $21,000 and cornerback Nickell Robey-Coleman says he was fined $10,000. Safety Aaron Williams was also fined, but wouldn't reveal how much. "It's up there," Williams said.

The three spoke to The Associated Press after practice Thursday, a day before the NFL discloses what players it has disciplined from the previous week's games.

Several punches were thrown during a shoving match between players and coaches that erupted about an hour before kickoff.

Blanton said the altercation started once quarterback Jacoby Brissett and rookie receiver Malcolm Mitchell jogged through Buffalo's defensive backs drills for a second time.

The Bills won 16-0.
