Panathinaikos will play Olympiacos in Game 2 of the Greek Basketball League finals on Sunday inside the Peace and Friendship Stadium in Piraeus.

Heading into their second meeting, after Panathinaikos won Game 1 of the three-game series 80-68, things got intense early when an altercation between Olympiacos fans and Panathinaikos owner Dimitris Giannakopoulos broke out, according to a basketnews.com report.

The report claims Giannakopoulos was seen arriving at the arena alongside the Panathinaikos team delegation before being met by a crowd of rival fans chanting insults at him. Furthermore, the situation escalated once the fans began chanting obscenities at Giannakopoulos' daughter.

Enraged by the chants, the team’s owner approached the scorer’s table and demanded the officials record the fans to throw them out of the arena. The referees responded by requesting Giannakopoulos' removal from the stadium, citing a gesture he made toward the crowd, which stands as grounds for expulsion, according to ERT3’s Live Broadcast.

The altercation occurred around 10 minutes before tipoff, during an already hectic buildup to Sunday’s game. Panathinaikos was looking to win Game 2 to take home the team's 22nd Greek League championship.

Their organization won the 2024 EuroLeague championship and the Greek Cup 16 times. Meanwhile, their rivals, Olympiacos, have won three Euro League championships and 14 Greek Championships.

They also have won 12 Greeks Cups and three Greek Super Cups. In the regular season, Olympiacos finished in second place at 20-2, while Panathinaikos ended in first place at an undefeated 22-0.

Olympiacos roster is led by former NBA players Evan Fournier and Sasha Vezenkov. Panathinaikos is led by fellow former NBA players Cedi Osman and Kendrick Nunn.
