New York Knicks head coach Tom Thibodeau revealed Julius Randle is still dealing with the ankle sprain he sustained last month.

Randle sat out the fourth quarter, scoring only seven points from 27 minutes on three-of-10 shooting, as the Knicks won 102-93 over the Cleveland Cavaliers on Sunday to go 3-1 up in their first-round playoffs series.

The Knicks power forward sprained his ankle on March 29 against the Miami Heat and missed the final fortnight of the regular season, before returning for this series, but is still finding his rhythm according to Thibodeau.

"The thing is, he had to work around the clock to get back," Thibodeau said. "That's what I love about Julius. He gives you everything that he has.

"There's 77 games, he sprains his ankle and then he works like crazy to get back, you know how important he is to the team, but to get back, to get ready to play - our medical people did a great job, but that's all him.

"He was working around the clock on that, he still is. That's the challenge that we have and that's what I respect about him. And we just got to get ready for our next game."

Randle is averaging 14.8, 7.0 rebounds and 2.3 assists during the four games in the series, with the next game on Wednesday in Cleveland.

"Julius is our horse," Thibodeau added. "He's given us everything that he has. A lot of guys probably wouldn't even be playing, so I knew that with the quick turnaround, probably impact him more than most players.

"He was out an extended amount of time. So we got multiple days here before the next game, he'll get a chance to get some recovery time."

Jalen Brunson, who insisted the series was "not over", scored a game-high 29 points, making five-of-nine triples with six rebounds and six assists for the Knicks, while R.J. Barrett added 26 points.

Cavs' All-Star Donovan Mitchell was kept to 11 points on five-of-18 shooting, while Darius Garland tried hard with 23 points and 10 assists.

"This is not over with," Mitchell said. "The way we lost sucks. We can't hang our heads and ultimately give up. We're not that type of group. Like I said, we'll be ready for Game 5."
