San Antonio Spurs head coach Gregg Popovich is stepping away indefinitely after suffering a health issue, ESPN's Shams Charania reported on Monday.
Popovich, 75, missed the Spurs' victory over the Minnesota Timberwolves on Saturday with an undisclosed illness.
Assistant coach Mitch Johnson took over head coaching duties on Saturday and is expected to be the interim head coach until Popovich returns, Charania reported.
“He’s not feeling well,” Johnson said of Popovich on Saturday. “This has happened before. I think everybody’s just always got to be ready for the next man up. We’ve had it with injuries and sometimes people get sick or don’t feel well or things come up in life. He’s just not feeling well.”
