New York Knicks All-Star Kristaps Porzingis may have suffered a serious injury.

The Knicks power forward posterized Milwaukee Bucks All-Star Giannis Antetokounmpo on Tuesday night, but his landing after was awkward, he clutched his knee and has now gone back to the locker room for evaluation.

Porzingis had to be helped off the ground by teammates and into the locker room. It was one of those unfortunately all-too-common basketball injuries that looks like it could be an ACL tear, or something close to it. Nothing is official yet as he will most likely have an MRI shortly.

Porzinigis gave a thumbs up when he left the floor and there was some speculation that the injury could have been just a hyper-extended knee and nothing more.

This would be devastating for the Knicks to lose Porzingis, whose stardom is their only hope at making the playoffs this season. They could potentially make a move this week before the deadline while an injury to Porzingis will only further complicate things.

In another odd twist, this would be the fourth All-Star that was drafted by LeBron James that has gotten injured and become unable to compete in the All-Star game in Los Angeles later this month. If this is indeed a severe injury for Porzingis, another replacement will be selected in the coming days from the Eastern Conference.
