The 46-year-old Serbian known as "Deki" suffered a heart attack during a private team dinner in Utah on Tuesday and despite life-saving efforts, died late Wednesday morning at the Salt Lake City hospital.
"It's the saddest thing I've ever been a part of in the NBA," Warriors head coach Steve Kerr told reporters on Monday.
"Where we lose someone so close to us and then more importantly, see his family suffer."
The Belgrade native, who joined the coaching staff in 2021 and helped the team win the 2022 NBA championship, leaves behind a wife and two children.
"These last five days have been full of all of the above. The shock, the emotion, and the extreme outpouring of love from all over the world," Kerr said.
Kerr added that the team had together watched the emotional tribute to Milojevic held prior to a game in Belgrade between two of his former clubs.
Kerr said there is "no handbook" for how to deal with such a devastating loss but said the players and coaches have rallied around each other and Milojevic's family.
Warriors center Kevon Looney remembered Milojevic as "positive, joyful and authentic."
"He was somebody who loved to teach," he said. "He loved to spread his knowledge and his love."
Before joining the Warriors, Milojevic spent the 2021 season as head coach of Buducnost in the Adriatic League in Montenegro. Prior to that role, Milojevic was head coach for Mega Basket in Belgrade for eight seasons.
In December 2019, Milojevic was named an assistant coach for the Serbian national team under Igor Kokoskov.
Milojevic also enjoyed a 14-year international playing career and was named the Adriatic League Most Valuable Player three times (2004-06).
The Warriors postponed their games against Utah and Dallas last week and will next face Atlanta in San Francisco on Wednesday.
