The 2025 NBA Cup, the league's third in-season tournament since its 2023 launch, begins Friday night with group play matches. The Boston Celtics are competing in Group B alongside the Philadelphia 76ers, Detroit Pistons, Orlando Magic, and Brooklyn Nets.
All 30 teams are divided into six groups of five, based on their conference. Each team plays four group games—one against each group opponent, with two games at home and two on the road. The top team from each group plus a wild card team from each conference (the second-place team with the best record) advance to the knockout rounds.
The Celtics started the group stage with a narrow 109-108 win over the Sixers. Despite entering 2024 as reigning NBA champions, they failed to progress past the group stage last year. Their goal in 2025 is to advance further in the tournament.
Advancement requires finishing first in the group or securing the wild card spot as the best second-place team in the conference.
