Spoelstra said Adebayo didn't undergo additional testing, just put a lot of ice on it.
"It's a little bit of everything," the coach said when asked if the injury was to his wrist/shoulder/arm. "This is a physical series. He'll be ready to go tomorrow."
Adebayo got tangled up with Celtics guard Jayson Tatum in the second half of Wednesday's Game 4 of the Eastern Conference finals. His left wrist appeared to get turned in the wrong direction, but he brushed off concerns about an injury lingering.
"I'm good," Adebayo said after the game. "Just a wrong turn ... wrong little movement, nothing major."
Spoelstra also didn't sound outwardly concerned postgame.
"He's just got a lot of ice on his body," Spoelstra said. "And that's where we are right now -- everybody's earning their ice."
