PHILADELPHIA (AP) — Philadelphia Phillies ace Zack Wheeler's season is over.

Wheeler was diagnosed with thoracic outlet syndrome and will require additional surgery that’s expected to sideline him for six to eight months, the team announced Saturday.

Wheeler had a follow-up evaluation following a procedure Monday to remove a blood clot from his upper right arm. After receiving a second opinion, it was recommended that Wheeler undergo thoracic outlet decompression surgery in the coming weeks. Such a surgery would threaten Wheeler’s ability to start the 2026 season on time.

“It’s disappointing, but everybody knows it’s out of our control,” Phillies manager Rob Thomson. “We’re happy he’s going to be healthy, because it’s a very serious thing that he went through.”
