Boston Celtics star forward Jayson Tatum is staying positive after undergoing surgery on Tuesday to repair his ruptured right Achilles tendon.

Tatum shared a picture of himself on Instagram Wednesday flashing a thumbs up sign from his hospital bed.

“Thankful for all the love and support,” the six-time All-Star wrote in the caption.

The Celtics shared the photo on their X account.

Tatum, 27, sustained the injury Monday night in Game 4 of their Eastern Conference semifinal series against the Knicks. New York beat the defending champions 121-113 to go up 3-1 in their best-of-seven set. Game 5 is Wednesday night in Boston.

Tatum was hurt when teammate Jaylen Brown fumbled the ball and Tatum made an attempt toward it. He suffered a non-contact injury and was in agony on the court, calling his own timeout with 2:58 remaining and grabbing at his ankle.
