Gregg Popovich stepped down as coach of the San Antonio Spurs on Friday, ending a three-decade run that saw him lead the team to five NBA championships, become the league’s all-time wins leader and earn induction into the Basketball Hall of Fame.

Popovich will remain as team president. Mitch Johnson, a Spurs assistant who filled in for Popovich for the season’s final 77 games, becomes the team’s head coach.

Popovich, 76, missed all but five games this season after having a stroke at the team’s arena on Nov. 2. He has not spoken publicly since, though had addressed his team at least once and released a statement in late March saying that he hoped to return to coaching.

Popovich’s career ends with a record of 1,422-869, which does include the 77 games — 32 wins and 45 losses — that were coached by Johnson this season. He also won 170 playoff games with the Spurs, the most by any coach with any one team and the third-most overall behind only Phil Jackson’s 229 and Pat Riley’s 171.

NCAA, Iowa State negotiate sports betting discipline >> The NCAA has taken disciplinary action against five current or former Iowa State football support staff members for combining to make more than 6,200 online bets totaling more than $100,000 on professional and college games, including men’s and women’s basketball games involving the Cyclones.

The five were identified during a state investigation into sports wagering activities in campus athletic facilities from 2021-23. They face no criminal charges.

In a negotiated resolution finalized last week, Jace Heacock, Chase Clark, Michael Dryer, Kyle Highland and Mason Williams acknowledged they knowingly violated NCAA sports wagering bylaws and all are subject to a one-year show-cause order through April 24, 2026.

Any of the five hired by another school’s athletic department will be required to attend the annual NCAA Regional Rules Seminar at his own expense and serve a two-week suspension during the show-cause period.

Iowa State’s athletic department declined to comment on the case.

The NCAA classified the violations as Level II for the individuals involved, meaning the breaches could compromise the integrity of the NCAA collegiate model.
