Don't lose a bet with Josh Green.
Ahead of the Dallas Mavericks' game against the Los Angeles Lakers on Wednesday, Doncic arrived at American Airlines Center rocking Josh Green's Australian Boomers national team jersey with a beanie pulled down over his face.
It's unclear why the Mavs star was rocking the green and gold, but it's safe to assume it's punishment for a lost bet with Green, who walked into the arena ahead of Doncic with a big smile on his face.

Doncic led Slovenia to an impressive run at the Tokyo Olympics this past off-season, before going down to Green and the Boomers in the bronze medal game.

It's safe to say the banter hasn't died down since Tokyo with Green telling ESPN earlier this year he's been having fun at Doncic's expense.
"I bring it up a lot actually. It's not off limits, I go there all the time," Green said.
It's all smiles for the Mavs right now as they continue their climb up the standings, sitting third in the Western Conference at 48-29.
