Miami Heat star guard Jimmy Butler says he will need an MRI on his right knee after he was injured in the first half of a play-in tournament loss to the Philadelphia 76ers on Wednesday.

Butler sustained the injury in the first quarter when he tried to fake out Kelly Oubre Jr. on a basket, only to have his knee buckle. He fell to the floor and Oubre appeared to land on top of him.

“I fell, he landed, and my knee just didn’t do well, I guess,” Butler said. “I don’t know. It’s not a good feeling, I can tell you that.”

Butler sank the free throw, exhaled, and missed the second one. He stayed in the game and finished with 19 points on 5-of-18 shooting in a 105-104 loss.

The Heat will host the Chicago Bulls on Friday night, with the winner getting the No. 8 seed and a playoff matchup with the league-leading Boston Celtics.

“We just need to get one and then we’ll worry about the next one,” Butler said.

It’s unknown whether Butler will be available to play that game.

“It felt like I couldn’t do much, which sucks with the timing of the game and everything,” Butler said. “I hope that I’m fine. I hope that I wake up tomorrow and can still stick-and-move. Right now, I can’t say that’s the case.”

Butler averaged 20.8 points in 60 games this season for the Heat, tied with Tyler Herro for the team lead.
