Golden State Warriors guard Klay Thompson underwent surgery Wednesday and is expected to make a full recovery from a late-season right Achilles tendon tear, a source told ESPN’s Adrian Wojnarowski.

Dr. Richard Ferkel, a leading ankle injury specialist, performed the surgery in Los Angeles and it was deemed a success, the source said.

Thompson, a five-time All-Star, tore his right Achilles tendon during training with several NBA players last week in Southern California. They did an MRI the next morning that revealed the severity of the injury.

Thompson, 30, missed all of last season after tearing the ACL in his left knee during Game 6 of the 2019 NBA Finals against the Toronto Raptors. The Warriors were optimistic that Thompson, who has spent more than a year rehabbing the injury, would return in full force for the 2020-21 season. Now they will spend another season without him on the court.

The injury is a huge blow to the Warriors, who went 15-50 in the NBA last season as they struggled without Thompson and Stephen Curry, who broke his left hand and left him out for more than four months.
