Luka Doncic requested a heckling fan be ejected during the third quarter of the Dallas Mavericks' 132-109 loss to the Phoenix Suns.

Dallas was outscored 43-20 in the quarter as Devin Booker scored 22 of his 46 points.

Doncic reacted to the heckler, a Suns fan who wore a Booker "El Valle" jersey while sitting in the second row behind the midcourt press area, late in the third quarter. The man shouted: "Luka, you're tired! Get your ass on the treadmill!"

Doncic stared at the fan for a few seconds then waved toward Mavs vice president of security Brian Kinzig, pointed at the fan and gestured that he wanted him ejected.

Doncic approached Kinzig on the court during the break between quarters, pointed at the fan again and requested for him to be ejected. 

Doncic took umbrage with the reporting of his request for the fan's ejection.

"He was cursing me the whole first half, too," said Doncic.

Asked why he didn't ask for the fan to be ejected during the first half, Doncic said: "Because I never would eject a fan. They paid for tickets, but I had enough. It's a little bit of frustration."
