Quincy Acy #4 of the New York Knicks scuffle with John Wall #2 of the Washington Wizards in the second half of their game at Madison Square Garden on December 25, 2014 in New York City.

*New York Knicks forward Quincy Acy has been suspended one game and Washington Wizards guard John Wall was fined $15,000 by the NBA on Friday for their roles in a Christmas Day brawl.

The Knicks’ Quincy Acy received a flagrant foul 2 and was ejected after a dustup with John Wall.

The NBA said in a statement Friday that it decided to suspend Acy because his flagrant foul initiated the confrontation. The league said it fined Wall because his actions escalated the incident.

Acy shoved Wall to the ground when the Wizards guard had the ball with 5:31 to play in Washington’s 102-91 victory. Wall jumped up and shoved him back. Things escalated from there and both players had to be separated by teammates.

Both Acy and Knicks coach Derek Fisher said Thursday that Acy did not throw a punch at Wall.

“I didn’t throw a punch. I got up and reacted, then I just grabbed him,” Acy said.

Acy explained that he was trying to foul Wall to stop the play because Knicks guard Pablo Prigioni was on the ground and his team was down a man on defense.

“It was just a foul. If somebody has a fast break and you step up and grab them, it’s the same concept,” Acy said.
