Deandre Ayton left the Portland Trail Blazers' loss to the Miami Heat on Tuesday with a sprained hand.
X-rays returned negative.
"I think there will be some further testing because he was in quite a bit of pain. I thought (Ayton) dominated that first half. Offensively, defensively, he dominated the game," said Chauncey Billups after the game.
Ayton, who suffered the injury in the first quarter but didn't leave the game until halftime, finished with 12 points and 10 rebounds.
