Baku marked the penultimate Karate 1-Premier League event of the season.

A season-ending leg had been due to take place in Los Angeles from October 7 to 9 after it was moved from Moscow due to the Russian invasion of Ukraine, but the American city is unable to host it as planned due to "unforeseen circumstances".

One more Premier League competition is planned this season, but dates and the venue are still to be announced.
