The two players confronted each other after Nuggets center Nikola Jokic was given a foul for charging into Trail Blazers forward Zach Collins.
As Barton seemed to get tangled up with a fallen Collins, he became involved in a shoving match with Curry. Tensions flared and the players had to be separated.
During the skirmish, Barton appeared to have poked Curry in the eye while Collins and Denver’s Torrey Craig were in a scuffle of their own.
All four players received technical fouls.
“[Barton] waited for a few people to get in between us, and when a few people were in between us, he put his finger in my eye,” Curry told reporters after the game, according to ESPN. “You know what I'm saying. I can't allow people to put their fingers in my eye.”
Barton said after the game he doesn’t think he’d be suspended for Saturday’s Game 7 and argued he was only defending himself from Collins who fell around him during the play.
“It ain't no beef,” he said, according to ESPN. “I wasn't even looking for that. I was just trying to protect myself. I guess he thought I was trying to stand on top of him and be tough. I was just trying to get out of the way before I got injured. He pushed me. I'm not going to let nobody push me. But that's nothing.”
The Trail Blazers won the game 119-108 to force a Game 7. The winner of the series will play the winner of the matchup between the Warriors and the Houston Rockets.
