Olympiacos (2019–2020) On 19 March 2019, Pokuševski made his
EuroLeague debut with
Olympiacos, in a 89–69 win over the German club
Bayern Munich, during the EuroLeague's
2018–19 season. He recorded 1 point, 2 rebounds and 1 assist, in one minute played during the game. Pokuševski became the youngest senior men's Olympiacos player to ever debut in the EuroLeague. At 17 years and 83 days old, he replaced
Georgios Printezis, who had previously debuted in the EuroLeague, at the age of 17 years and 229 days, as the club's youngest-ever EuroLeague player. For the
2019–20 season, Pokuševski was assigned to play in the
Greek A2 League, the country's second-tier league, with Olympiacos'
reserve team,
Olympiacos B. He initially played for the senior EuroLeague club's
practice squad. During the season, Pokuševski missed almost 3 months of playing time, due to a
knee injury. Pokuševski started in eight of his 11 appearances in the Greek A2, averaging 10.8 points, 7.9 rebounds, 3.1 assists, 1.3 steals and 1.8 blocks in 23.1 minutes per game. He shot 40.4 percent from the field, 32.1 percent from three-point range, and 78.3 percent from the free-throw line. In the middle of the season, Olympiacos' main EuroLeague team was riddled with injuries, and Pokuševski was called up to the senior team. He played two minutes in his only EuroLeague game of the season, before the league's season was suspended due to the
COVID-19 pandemic in Europe. On 24 April 2020, Pokuševski declared for the
2020 NBA draft. Pokuševski was under contract with
Olympiacos through the end of the 2023–24 season. The contract's

lottery pick. Following selection in the NBA draft, Pokuševski left Olympiacos on 24 November 2020.

2021–22 NBA season, averaging 7.6 points, 5.2 rebounds, and 2.1 assists. In July 2022, Pokuševski joined the Thunder for the
