Butler took issue with Paul tossing the ball off Heat sharpshooter Duncan Robinson to gain possession near the end of the first half and he sent a warning to the Thunder floor general postgame.
"You're not gonna throw the ball at my teammate like that," Butler said, per 790 The Ticket's Brendan Tobin. "I'll get a turnover, get an offensive foul. We don't do that here. You mess with one of my guys, especially one of my shooters, then you got to deal with me and everybody else."
Butler took matters into his own hands on the ensuing possession by aggressively shoving Paul to the floor while driving, which drew an offensive foul.
Robinson didn't seem as bothered by what transpired when asked about the altercation.
"We kind of just went back and forth, nothing out of the ordinary for an NBA game," Robinson said. "He's a really talented player, well renowned, I have a lot of respect for him. But he also competes, and I'm not one to back down from a challenge in that regard ... heat of the moment type of thing."
Paul and the Thunder wound up getting the last laugh, coming back from a 22-point deficit to seal the victory.
