If you're a fight promoter, the least you can do is have some decent medical staff on hand for when people naturally get busted up and hurt. Because, you know, you're putting on fights and that's inevitably what's going to happen. This has been the creed since back in the day when dudes were fighting in barns. At least (for the most part) EMTs were on site with an ambulance. Hell, even wrestling shows with dudes smashing lightbulbs over each other have proper medical personnel. It's just the cost of doing business.
Then we have ONE FC. The biggest fight promotion in Asia by default, and a fight promotion that seems to care about human life.
