Spurs coach Gregg Popovich has medical emergency while recovering from stroke: report

Popovich reportedly did not suffer any life-threatening injuries or illnesses, and he was alert by the time he entered the ambulance.

The team said he was expected to make a full recovery. Mitch Johnson has been leading the Spurs in Popovich's absence. 

In December, six weeks after his stroke, Popovich had not ruled out a comeback, saying tongue-in-cheek, "No one is more excited to see me return to the bench than the talented individuals who have been leading my rehabilitation process. They've quickly learned that I'm less coachable."

"Mitch Johnson and his staff have done a wonderful job, and the resolve and professionalism the players have shown, sticking together during a challenging season, has been outstanding," he said in a statement at the time. "I will continue to focus on my health with the hope that I can return to coaching in the future."
