Fans will have to wait a little while longer for the return of ONE Championship, because the promotion has called off its next event. ONE Championship 57 was scheduled to take place July 29 in Surabaya, Indonesia. The promotion today announced the card has been “postponed until further notice,” though, citing “logistical issues” as the reason behind the decision. The Asia-based organization has hosted seven events in Indonesia to date, however, all had taken place in Jakarta. The planned event marked the first venture to Surabaya, and it’s unknown what role the location played in the situation. Prior to the postponement, ONE Championship 57 featured a flyweight championship main event between unbeaten titleholder Kairat Akhmetov (23-0) and challenger Adriano Moraes (15-2)
