SAN ANTONIO — Former Spurs guard Tony Parker, a four-time champion, told ’s The Undefeated that he is retiring after 18 seasons.

“I’m going to retire. … I decided that I’m not going to play basketball anymore,” Parker told The Undefeated.

Parker retires at the age of 37 with 1,254 regular-season games played, having averaged 15.5 points, 5.6 assists and 2.7 rebounds per game.

The Spurs took Parker with the 28th overall pick in the 2001 draft. He formed a core with Tim Duncan and Manu Ginobili that won four titles. The 6-foot-2, 185-pound Parker also became the first an to become an Finals MVP (in 2007).

The six-time all- selection played for the Spurs from 2001 to 2018 and played his final season with the Charlotte Hornets in 2018-19.

Parker told The Undefeated in an interview on June 1 in San Antonio that he is at peace with his decision to retire. He wanted his retirement announcement to be released Monday.

“A lot of different stuff ultimately led me to this decision,” Parker said. “But at the end of the day, I was like, if I can’t be a Tony Parker anymore and I can’t play for a championship, I don’t want to play basketball anymore.”

Parker also tweeted about his retirement Monday.

Parker will be best known for being a member of the Big Three for the Spurs with Duncan and Ginobili while being coached by .

They won titles together in 2003, 2005, 2007 and 2014 and played together from 2002 to 2016. One of the most successful trios in history, they played over 1,000 games together. Duncan retired in 2016, Ginobili retired in 2018, and both have since had their jerseys retired by the Spurs. The team is expected to retire Parker’s No. 9 jersey as well.

Parker told Duncan and Ginobili he was retiring recently during lunch in San Antonio.

“They were like, ‘Are you sure?,'” Parker said. “And I was like, ‘Yeah, I’m sure.’ And so, they’re like, ‘If you’re sure, man, I’m so happy for you. I’m so happy for you. We had a great run and can’t wait to beat you up on and spending more time together.’

“… We’re always going to be remembered together. But it was great to share that moment with them. It’s crazy. We came from three different backgrounds and came together.”

Parker is already busy in retirement.

He is opening the Tony Parker Adequat Academy international school in his hometown of Lyon, France, in September. He is currently the owner and president of ASHVEL, a French professional basketball men’s and women’s club based in Lyon. While Parker intends to spend more time working closely with ASHVEL and his new school, he plans to continue to have a home base in San Antonio.

Parker also wants to be an owner one day.

“That is one of my dreams,” Parker said. “Right now, I’m focusing on ASHVEL and having a great experience. We’re building a new arena right now, and we’re gonna enter the Euroleague and the Euroleague is growing very fast. But the ultimate is to be one day an owner in the . And so I’m already having talks with different people, and they’re looking at what I’m doing in France.

“It takes a lot of work, but I love it. I love it. So maybe one day, if it’s the right opportunity and it’s something that I definitely want to do. I’m just gonna wait for the right opportunity.”

Parker had said in recent years that he wanted to play 20 seasons in the . By retiring, he ends up two seasons shy of that goal. Parker turned down a player’s option for next season with the Hornets that would have paid $5.25 million.

But don’t expect the busy Parker to change his mind and return to the , even if he could go back to the Spurs.

“I’m at peace with it,” Parker said. “It’s been a long time that I’ve been in peace with that decision because I’ve prepared myself for that too, with all the stuff that I’m doing, the two teams I own in France and my international school opening in September. I have so much stuff going on that I’ve always been at peace with that decision.

“When it comes, I’ll be ready to leave it to the young guys. The game of basketball is for young guys. So that’s why for me, I understood very early, that when it’s time to [retire], I’ll be fine with it.”
