Jimmy Butler is listed as questionable for Tuesday's Game 2 after receiving treatment on his sprained ankle.
Erik Spoelstra said that Butler will likely be a game-time decision.
"He's doing treatment around the clock. Probably won't have any update until before the game," said Spoelstra on Monday.
Butler was injured with 5:05 left in the fourth quarter of Game 1, though he stayed in the game.
"Knowing Jimmy, he might mess around and try to play or whatever, not play, we don't know yet. So we'll see what type of shape he's in with that ankle. But we'll be ready for whatever," added Caleb Martin.
