RJ Barrett suffered a sprained ankle in the third quarter of the New York Knicks' 121-98 loss to the Phoenix Suns.
Barrett, who has played in 41 out of 42 games this season, will be re-evaluated on Friday.
"They're going to reevaluate it tomorrow. That's all I know. … It hurts. I don't know, I've never really been hurt before. No clue (about the severity) yet, it just hurts and we'll see what happens with the swelling and everything and then come in tomorrow and evaluate it," said Barrett.
Barrett ended the night with 7 points and 3 rebounds.
