The Spurs are preparing for longtime head coach Gregg Popovich to retire within the next year or two, league sources tell Jordan Schultz of ESPN.

According to Schultz, the organization is beginning an “extensive” search to identify Popovich’s successor. That search will cover both external and internal candidates.

In the years leading up to the Tokyo Olympics, there had been speculation that the event would be Popovich’s swan song. However, even after leading Team USA to gold in Japan following a one-year delay, he’s returning to the sidelines in San Antonio for the 2021/22 season.
