SAN ANTONIO (AP) — San Antonio Spurs coach Gregg Popovich is out indefinitely while you are recovering from an illness.

San Antonio announced that Popovich would not travel with the team during their current road trip at the Los Angeles Clippers on Monday and in Houston on Wednesday. The Spurs host the Portland Trail Blazers on Thursday.

Mitch Johnson will serve as interim coach in Popovich’s absence.

Johnson was notified about 2 1/2 hours before Saturday’s tip against the Minnesota Timberwolves that the 75-year-old Popovich was unavailable due to an undisclosed illness.

“He’s not feeling well,” Johnson said. “This has happened before. I think everyone just has to always be ready for the next guy. We’ve had it with injuries and sometimes people get sick, don’t feel well or things happen in life. He just doesn’t feel well.”

It was Johnson’s third time serving as head coach in Popovich’s absence. Former assistant coaches Tim Duncan and Becky Hammon also served as Spurs head coach for the past five seasons due to an illness or medical procedure for Popovich.

Without Popovich, the Spurs defeated the Timberwolves 113-103 behind 25 points from Keldon Johnson and a vintage game from Chris Paul (15 points and 13 assists).

Popovich is the NBA career leader with 1,390 wins and another 170 postseason wins while winning five NBA titles. He is in his 29th season, all with San Antonio.
