Giannis Antetokounmpo regrets letting his emotions get the better of him.

The Milwaukee Bucks star was suspended for one game after headbutting Washington Wizards centre Moritz Wagner during Wednesday's game (all times AEST).

Antetokounmpo was ejected from the game after the incident occurred in the second quarter, with the Bucks going on to win 126-113.

The star forward admitted after the game he let his emotions get the better of him after he was fouled multiple times in the quarter.

“If I could go back and turn back time and go back to that play, I wouldn't do it. But at the end of the day, we're all human, we all make mistakes.” Antetokounmpo said.

“I think I've done a great job all year, in my career, of keeping my composure and focusing on the game, but like I said, we're human, we make mistakes. But at the end of the day, learn from it, keep playing good basketball and keep moving forward.

“I think it was just the whole, like, build-up of dirty plays in my mind. Guys tripping me, guys falling in front of my feet, holding me, hitting me

“I don't have anything against Wagner, it wasn't just him," Antetokounmpo said.

Antetokounmpo will miss the next game against Memphis Grizzlies, who are fighting fighting for a place in the playoffs.

The Bucks have already clinched the top seed in the Eastern Conference, with Antetokounmpo is expected to make a big impact in the postseason.
