San Antonio Spurs hired Udoka as an assistant coach under
Gregg Popovich. Udoka won his first NBA championship when the Spurs defeated the
Miami Heat in five games during the

LaMarcus Aldridge's decision to join the Spurs in 2015 as they were teammates on the
Portland Trail Blazers during Aldridge's
rookie season.
Philadelphia 76ers (2019–2020) On June 26, 2019, Udoka was hired as an assistant coach of the
Philadelphia 76ers. His head coach on the 76ers at the time,

Brooklyn Nets (2020–2021) On October 30, 2020, the
Brooklyn Nets hired Udoka as an assistant coach.
Boston Celtics (2021–2023) 2021–22 season On June 23, 2021, it was reported that the
Boston Celtics had hired Udoka as their head coach, replacing
Brad Stevens, who was promoted to President of Basketball Operations a few weeks prior. The hiring became official five days later. Udoka became the franchise's sixth African-American head coach, as well as the first head coach of African origin in NBA history. Stevens later stated that he hired Udoka as his own replacement as head coach since Udoka had "a great approachability". Although the Celtics began the
2021–22 season with an 18–21 record, they began a turnaround in January and finished as the #2-seed in the Eastern Conference with a 51–31 record. During the turnaround, Udoka earned two Eastern Conference Coach of the Month awards, one in February and another for March and April. During the playoffs, the Celtics swept the
Brooklyn Nets in the first round before beating the
Milwaukee Bucks in seven games during the Eastern Conference Semifinals. The Celtics went on to defeat the
Miami Heat in seven games during the
Eastern Conference Finals to make their first
NBA Finals appearance since
2010. However, the Celtics lost the
2022 NBA Finals to the
Golden State Warriors in six games despite a 2–1 lead.
2022–23 season On September 22, 2022, the Celtics suspended Udoka for the entire
2022–23 season for violating team policies. He was disciplined for engaging in an improper intimate relationship with a female staff member. Although the Celtics initially believed that the relationship was consensual, the woman later accused Udoka of making unwanted comments towards her. He issued an apology after being suspended, but Udoka chose not to resign from his position due to the violation. Assistant coach
Joe Mazzulla replaced Udoka as interim head coach. On February 16, 2023, Mazzulla was named the team's permanent head coach after leading the Celtics to a league-best 42–17 record at the
NBA All-Star break, signaling the end of Udoka's tenure in Boston.
Houston Rockets (2023–present) 2023–24 season On April 24, 2023, it was reported that the

In his first season with the team, the Rockets finished with a 41–41 record and narrowly missed the playoffs.
2024–25 season Udoka was named Western Conference Coach of the Month in January 2025 after the Rockets won 11 of their 15 games that month. They ultimately finished with a 52–30 record to clinch the
Southwest Division for the first time in six years and finished as the #2-seed in the conference for the
2025 playoffs, behind the No. 1 seed
Oklahoma City Thunder. However, the Rockets lost to the Warriors in seven games during the first round of the playoffs.
2025–26 season On June 19, 2025, Udoka signed a multi-year contract extension with the Rockets. In the midst of a blockbuster trade where
Kevin Durant was acquired by the Rockets, they finished once again with a 52–30 record, this time as the #5-seed in the conference for the
2026 playoffs, where the
Los Angeles Lakers were waiting for them. However, despite
Durant remaining healthy in the regular season, with his near-total absence in the playoffs, the Rockets lost to the Lakers in six games during the first round. ==National team career==
