On 9 October, the Euroleague Basketball Disciplinary Judge has declared 20–0 win to Frutti Extra Bursaspor.[47] Ten day late, Euroleague Basketball confirmed the modification of the Special Regulations and removed the 20-0 results for all games.[48] Afterwards, the game was rescheduled to 9 November 2020. Due to having missed two games each so far due to the COVID-19 pandemic, Olimpija and Bursaspor made the rare agreement to play this Round 2 game, which was supposed to have been in Ljubljana, on the court of the visiting team. One result of that decision is that they will play again in 48 hours at the same arena, Tofaş Nilüfer Salonu, on Wednesday in their regularly scheduled Round 7 game in Group D.
Note: The game was originally scheduled to be played on 28 October. Promitheas requested the suspension of the game due to local legislation imposing quarantine measures on the team.[49] Afterwards, the game was rescheduled to 10 December 2020.
