Dwyane Wade is listed as day-to-day with a bruised right knee.
"He's been dealing with this for over a month," Erik Spoelstra said. "It's getting better. But he plays a physical game. He was on the ground four or five times [Thursday] night. One was a collision where he got fouled in the first half, he got hit in the elbow, he got hit in the face, he got hit in the knee, all in one play.
"But he's fighting through it. Some days are a little bit better than others, depending on the collisions he has from the night before."
Wade struggled offensively in Thursday's Game 3 against the Milwaukee Bucks, shooting just 1-for-12 from the field with four points and six turnovers.
"He came over to me at one point," Spoelstra said of Thursday's game, "and I just made sure, 'Hey, you OK?' And he said, 'I'm good to go Coach. Whatever we need.' "
Wade recorded five steals, nine rebounds and 11 assists in 28 minutes.
