San Antonio Spurs head coach Gregg Popovich will be sidelined the next two games after undergoing "a minor medical procedure" on Friday, the team revealed, per ESPN's Tim MacMahon.

Popovich will miss Friday's game against the New Orleans Pelicans and Sunday's game against the Phoenix Suns. He'll return when the Spurs host the Houston Rockets on Thursday.

Brett Brown is set to step in for Popovich over the next two games. He previously served as head coach of the Philadelphia 76ers from 2013 to '20, when he was replaced by current bench boss Doc Rivers.

In addition to his latest absence, Popovich missed a 123-92 loss to the Los Angeles Lakers on Nov. 20 with an illness. Brown also stepped in to coach during that game.

The Spurs enter Friday's game 14th in the Western Conference with a 6-16 record. The franchise is in the midst of a rebuild after having failed to make the playoffs in each of the last three seasons.

Keldon Johnson and Devin Vassell are two of San Antonio's best players and are a duo that it will likely want to build around in the coming years.

Popovich has been head coach of the Spurs since 1996. In his 27 seasons at the helm, the Spurs are 1,350-717 and have won five NBA titles, the most recent coming in 2014, when they defeated the Miami Heat in five games.

Popovich will turn 74 next month, and his time in the NBA is undoubtedly winding down.
