An argument in the huddle between Rudy Gobert and Kyle Anderson led to Gobert punching Anderson, sources described to Adrian Wojnarowski of ESPN. 

Anderson reportedly told Gobert to block some shots, with Gobert responding by telling Anderson to grab a "bleeping" rebound.

Gobert then lost his temper when Anderson told him to "Shut the f--- up, b----."

"That's what set Rudy off," a source told Wojnarowski.

Gobert then tweeted Anderson an apology after the game. 

"Emotions got the best of me today. I should not have reacted the way i did regardless of what was said. I wanna apologize to the fans, the organisation and particularly to Kyle, who is someone that i truly love and respect as a teammate," wrote Gobert.

Gobert nearly didn't play in the game after hurting his back on Saturday against the Spurs.

Anderson said afterwards that the situation would be handled within the team.

"We'll move forward. We want to win games. It is what it is. We'll keep it in house," said Anderson.
