In September 2016, after the withdrawal of AEK, Partizan NIS and Stelmet Zielona Góra due to the pressures and threats they received from FIBA and National Federations,  Euroleague Basketball announced that will review candidate clubs to fill the vacancies, but finally reduced to 20 teams.

Round and draw dates

Draw
The draw was held on 7 July 2016, 13:15 CEST, at the Mediapro Auditorium in Barcelona. The 24 teams were drawn into four groups of six, with the restriction that teams from the same country could not be drawn against each other. For this purpose, Adriatic League worked as only one country. For the draw, the teams were seeded into six pots, in accordance with the Club Ranking, based on their performance in European competitions during a three-year period and the lowest possible position that any club from that league can occupy in the draw is calculated by adding the results of the worst performing team from each league.

The rounds were 12 October, 18–19 October, 26 October, 2 November, 9 November, 16 November, 23 November, 30 November, 7 December, and 14 December 2016.
