This is due to the fact that Mariupol on the eve of the next stage of the League of Europe and because of this the team will have to hold at least two additional duel.
Because of the success of Mariupol, UPL will be forced to transfer the match of this team against Dynamo. Both teams are participating in European competition, and therefore play on August 11th round will not work.
According to the Rules of the ULL, the interval between two official matches must be at least two calendar days. Dynamo will play with Slavia on August 14, and Mariupol with Bordeaux on the 9th. Thus, to hold a match between Mariupol and Dynamo in the interval between 9 and 14 August is impossible.
Most likely, the match will be postponed to September 26th - this is the base date for the 1/16 finals of the Ukrainian Cup, but Dynamo and Mariupol do not take part in this stage.
