Joe Mazzulla's grim Jayson Tatum injury update spells doom for Boston Celtics

Boston Celtics coach Joe Mazzulla shared an update on Jayson Tatum, who suffered a right leg injury. Tatum was having an all-time performance in Game 4 of the Eastern Conference semifinals on Monday, when he went down after trying to dive for a ball.

Speaking to reporters after the game, Mazzulla was asked about an update on Tatum's status. The Celtics superstar seemingly ruptured his Achilles tendon in his right leg while trying to go after a loose ball late in the fourth quarter. The championship-winning coach revealed that Tatum will undergo further testing.

Mazzulla also shared that it was a lower-body injury, and it was tough for him to watch his star player get carried because he couldn't walk.

"It's tough to watch a guy like him get carried off like that," Mazzulla said, according to SB Nation's Noa Danzell.

With the Boston Celtics down late in the fourth quarter, Jaylen Brown lost the ball against Mikal Bridges on the dribble. The ball was loose, and Jayson Tatum tried to dive for a loose ball. However, his right leg buckled as he went down in pain with a non-contact leg injury.

According to Dr. Jesse Morse on X, formerly known as Twitter, Tatum might have suffered a torn Achilles tendon in his right leg. The classic signs of the leg giving out and the player immediately grabbing it in pain were there. It could also be a sprained ankle or fracture, but it appears unlikely due to the footage available.

If it's a torn Achilles tendon for Tatum, he'll be out for the rest of the playoffs and could miss the entire 2025-26 NBA season. It's a tough blow for the defending champions as they return home to Boston down 3-1 in the series against the New York Knicks.
