SAN ANTONIO — Basketball Hall of Famer Gregg Popovich is recovering from what the San Antonio Spurs described as a mild knock, although there is no timetable for the NBA’s longest-tenured coach to return to the sidelines.

Popovich suffered the stroke Nov. 2 at the Spurs’ arena, the team said Wednesday, and has already begun a rehabilitation program with the belief that he will make a full recovery. The team did not release other details, including what after-effects of the stroke — if any — he is experiencing.

“It’s a difficult time for everybody,” Spurs general manager Brian Wright said. ”Coach Pop has been the leader of this organization for the last three decades. We’ve all met or know people who just have a different aura, a different presence about them. Clearly, he is one of those people. When we walk into the building every day, we feel that leadership, we feel that presence, and so if we don’t have him there, it’s clearly a void. And we miss him.”

Popovich, 75, is the NBA’s all-time wins leader, having led the Spurs to five championships, plus led USA Basketball to a gold medal at the 2021 Tokyo Olympics. He is 29 season as manager of Spurs. .

”He’s doing well. He is doing well. … He’s tough, he’s a fighter and he’ll work,” Wright said. “We’re all here for him, but he’s doing well.”

Assistant coach Mitch Johnson served as interim head coach in Popovich’s absence. The Spurs play at home against Washington on Wednesday, and this will be the seventh straight game Johnson will replace Popovich.

”Mitch was great,” Spurs rookie Stephon Castle said Wednesday before the team announced details about Popovich’s health. “Even when Pop was here, he always had a voice in our gardens and in our locker room. Our philosophies have not been changed.”

A stroke occurs when blood flow to part of the brain is blocked or if a blood vessel in the brain bursts. This deprives the brain of oxygen, which can cause brain damage that can lead to difficulty thinking, speaking and walking, or even death. Strokes can lead to difficulty speaking, paralysis or loss of movement of certain muscles, memory loss, and more.
