Kristaps Porzingis left the Dallas Mavericks' 115-110 win over the Los Angeles Lakers in the third quarter due to a sprained ankle and did not return.
Rick Carlisle said he had no updates on the severity of the sprain.
"Uncertain as to the severity. We're hoping it's not too severe. I don't think he's been ruled out for Saturday yet, but with ankles, a lot of it's about how the player's feeling the next morning.
"So, we'll see where he is tomorrow. He was in pretty good spirits after the game, and he is walking. He isn't in a [protective] boot or anything at this point," said Carlisle.
Thursday's game represented only the fourth time that Porzingis had played in a back-to-back this season.
