John Wall and Jae Crowder had to be separated on Wednesday after the Boston Celtics' 117-108 win over the Washington Wizards.

Crowder could be seen putting his finger in Wall's face after the two exchanged words, and Wall appeared to land a quick open-hand slap before teammates and staffers rushed in to prevent a further escalation. Wall appeared to take another swipe at Crowder.

Five Boston police officers stood guard between the two locker rooms after the game.

"Just some altercation. We knew there was going to be some trash-talking," Wall said. "We knew it was going to be a physical game. That's all it was: Just a little trash-talking and a physical game."

Crowder didn't care to discuss what flared the incident.

"I don't know what you're talking about. I ain't got no comment about that," he said. "You want to talk about the game? Anyone want to talk about the game?"
