Giannis Antetokounmpo was ejected from Milwaukee's game against the Washington Wizards on Tuesday night after the NBA MVP head-butted Moritz Wagner.
With 8:50 remaining in the first half, Wagner took a charge from Antetokounmpo, who didn't like the offensive foul call in what had become a physical game.
During a break in the action with Milwaukee challenging the call, Antetokounmpo approached Wagner, exchanging words with the Wizards power forward before head-butting him. He was immediately ejected from the game.
Antetokounmpo had 12 points and nine rebounds in 10 minutes before exiting the floor.
Milwaukee went on to win what was essentially a meaningless contest 126-113. The Bucks have already clinched the top seed in the East, while the Wizards, who are winless in the bubble, have already been eliminated from playoff contention.
Antetokounmpo's head-butt could draw a punishment from the league and keep him out of the team's final seeding game against the Memphis Grizzlies on Thursday.
Earlier this week, Antetokounmpo was named as one of the three finalists for the 2020 MVP award.
