Golden State Warriors assistant coach Dejan Milojević, a mentor to two-time NBA MVP Nikola Jokic and a former star player in his native Serbia, died today in Utah after suffering a heart attack, the team announced. Milojević, part of the staff that helped the Warriors win the 2022 NBA championship, was 46.

Milojević died in Salt Lake City, where he was hospitalized after the medical emergency happened during a private team dinner on Tuesday night. The Warriors had been scheduled to play the Utah Jazz tonight, a game the NBA postponed.

“We are absolutely devastated by Dejan’s sudden passing,” coach Steve Kerr said in a statement released by the team. “This is a shocking and tragic blow for everyone associated with the Warriors and an incredibly difficult time for his family, friends, and all of us who had the incredible pleasure to work with him.”

Milojević was in his third season with the Warriors. He previously coached in Serbia — where he once worked with a young Jokic before the now-Denver Nuggets star came to the United States — along with Montenegro. He had been a head coach for eight years in Europe and previously was an assistant coach for the Serbian national team alongside current Atlanta assistant Igor Koskoskov.

“The NBA mourns the sudden passing of Golden State assistant coach Dejan Milojević, a beloved colleague and dear friend to so many in the global basketball community,” NBA Commissioner Adam Silver said. “In addition to winning the 2022 NBA championship in his first season with the Warriors and mentoring some of the best players in the world, Dejan had a decorated international playing career and was a distinguished head coach in his native Serbia.”

Milojević worked with Jokic, Los Angeles Clippers center Ivica Zubac, Orlando center Goga Bitadze and Houston center Boban Marjanovic, among others, during his time as a coach in Europe. Kerr said he originally learned of Milojević from Kent Lacob, the son of Golden State owner Joe Lacob. And when the Warriors went through some staff changes in 2021, Kerr decided to pursue Milojević.

It took some convincing, but Milojević finally agreed to take the offer. Kerr was thrilled.

“I immediately saw what Kent was talking about,” Kerr said in a video produced by the Warriors last year. “He was so great to be around. At the same time, he had this amazing basketball background both as a player and a coach. It made so much sense for us to bring Deki in.”

Milojević won three consecutive MVP awards in the Adriatic League, taking those trophies in 2004, 2005 and 2006 when the 6-foot-7, 240-pound power forward was at the peak of his playing career. Jokic would be MVP of that league in 2015, a year after current Golden State forward Dario Saric was MVP there.

No player has more Adriatic MVPs than Milojević, and the stories of some games in his youth were legendary. Among them: how he scored 141 points as a 14-year-old in 1991, 83 of those points coming in the second half after his coach ordered he take all the shots.

“I teach all my players that basketball is not a job, but that they should enjoy the game,” Milojević told Bosnian radio-television outlet RTV in a 2018 interview. “Because if you want to do something for the next 20 years, then you have to love it a lot. It’s not easy to endure all these efforts if you don’t like something. Only those who have a sincere love for the game can handle everything with great success.”

Before joining the Warriors, Milojević had prior NBA experience through Summer League assistant-coach stints with Atlanta, San Antonio and Houston.

Tributes began pouring in after Milojević’s death was announced, including from the Spanish club Valencia, where he spent two seasons. “The Club wants to send his family a lot of encouragement and strength in these difficult times, and convey all our support to them,” read Valencia’s statement.

Added Dylan Ennis, a longtime international pro who was once coached by Milojević: “You were not only a basketball master, you were an amazing human being. You will be missed by so many.”

A rescheduled date for the Warriors-Jazz game was not immediately announced. The Jazz said tickets for today would be honored at the rescheduled game.
