One Championship action was set to resume on April 17 and April 24, but that is no longer the case.
Chatri Sityodtong, who is the CEO of One Championship, has announced through Facebook that all One Championship events in April have been postponed due to the coronavirus (transcript via MMA Fighting):
“Unfortunately, ONE Championship will have to postpone its closed-door, audience-free events for April due to new COVID-19 restrictions. To extinguish the recent growth of the coronavirus, the Singapore Government has wisely ordered a partial lockdown of the country, whereby effective tomorrow (April 7th) onwards, only essential services (such as food, healthcare, and transportation) are allowed to operate. Additionally, major countries (China, Thailand, Singapore, Australia, Russia, India, Vietnam, Japan, etc) have temporarily closed their borders. We are living through the most extraordinary of times. The good news is that these short-term restrictions will undoubtedly slow down the coronavirus, and flatten the curve. To be clear though, it needs all of us to work together with vigilance. The most important thing that we can do as individuals is to follow the strict orders of our respective governments and to practice social distancing, good hygiene, and telecommuting. The virus cannot spread if we all stay at home. It really is as simple as that. Let us join hands in this fight and stand united as ONE.”
The promotion is set to return on May 1 and May 8 in Singapore, but the status of those events could be unknown as well due to the coronavirus outbreak.
