OAKLAND, Calif. — Golden State Warriors star Kevin Durant announced Wednesday on social media that he underwent surgery for a ruptured right Achilles tendon.

Durant revealed the severity of his injury two days after getting hurt during Game 5 of the NBA Finals in Toronto in his return following being sidelined for a month with a right calf strain. The 30-year-old posted a photo on Instagram showing himself in a hospital bed and wrote: “I wanted to update you all: I did rupture my Achilles. Surgery was today and it was a success, EASY MONEY.”

Just 15 minutes before Durant went public, Warriors coach Steve Kerr said during a finals media availability that he didn’t yet have a formal update on Durant. Durant has made his own announcements before, such as writing on The Players’ Tribune website about his decision to leave Oklahoma City to join Golden State in July 2016.

Kerr said the team had no idea that Durant risked a serious Achilles injury by returning from a strained calf.

After the game Monday, a teary, emotional general manager Bob Myers asked anyone who was looking to place blame to do so on him — not Durant, the medical staff or athletic trainers who worked so tirelessly to get him back.

Kerr said he also understands people wanting to point blame somewhere, though he noted, “Kevin checked all the boxes, and he was cleared to play by everybody involved,” including doctors from within the organization and from the outside.

“Now, would we go back and do it over again? Damn right,” he said. “When we gathered all the information, our feeling was the worst thing that could happen would be a re-injure of the calf. That was the advice and the information that we had. At that point, once Kevin was cleared to play, he was comfortable with that.”
