On 12 March 2020, the ABA League Assembly temporarily suspended its competitions due to the COVID-19 pandemic.[1] On 27 May 2020, the ABA League Assembly canceled definitely its competitions due to the COVID-19 pandemic.[2]
The Final tournament would have been played on 21–22 March 2020 at the Železnik Hall, Belgrade.[3] Cibona U19 was the defending champion and as a consequence of the COVID-19 pandemic, the ABA League Assembly decided not to recognize any team as the champion for the season.
Twelve under-19 teams are participating in the 2019–20 Junior ABA League season and they are divided into two groups in the first stage. In the group stage, all teams will face each other team within a group in a round-robin system. The two best-placed teams of each group will advance to the final tournament. At the final tournament, the teams will play two games – the semifinal and the final or third-place game. The winner of the final tournament will become the 2019–20 ABA Junior Tournament Champion.[4]
