An MRI confirmed that New York Knicks All-Star Kristaps Porzingis had torn the ACL in his left knee and will be out for the rest of the season, the team announced.

Porzingis injured his knee during the second quarter of the Knicks 103-89 home loss to the Milwaukee Bucks Tuesday night. The 22-year-old landed on the foot of Bucks Giannis Antetokounmpo after a dunk attempt and immediately grabbed his leg in pain.

The Knicks expect their young star to miss a minimum of 10 months, though the team had not yet established a timetable for surgery to repair the injury, ESPN reported. Porzingis averaged 22.7 points, 6.7 rebounds and 2.4 blocks per game this season.

The 7-foot-3 Latvian was the cornerstone of a rebuilding effort the Knicks put forth after trading away veteran Carmelo Anthony to the Oklahoma City Thunder for Doug McDermott and Enes Kanter in September.

"I’ll reach out to him tonight," Anthony told reporters during an interview after Tuesday’s victory over the Golden State Warriors. "It’s sad to know that injury, that type of game’s he’s been having, that growth that he’s had … as a friend, forget basketball, as a little brother it’s hard to see anyone go through that."

Porzingis will miss his first All-Star game where he was voted to play on "Team LeBron" alongside LeBron James, Kyrie Irving, Kevin Durant and others Feb. 18.

"Was hoping for the best news when I saw the play after the game," James tweeted. "Best wishes and have a speedy healthy recovery @kporzee."

The Knicks also lost sharpshooter Tim Hardaway Jr. who left Tuesday’s game with a knee injury. Hardaway had missed 20 games this season with a stress reaction in his left leg, the New York Post reported.

"Damn!!! Get well soon @kporzee. Praying on a speedy recovery," Hardaway Jr. tweeted.
