As per his Facebook:
This is the thanks I get for making a certain promoter cash. A $1,500 bill just for anesthesia. And waiting on my bill for the other $1,200-1,500 [for] surgery... and with people running around doing amateur fighters like this [you] wonder why MMA is not legal in New York. Thanks a lot, bud. I'll be sure to never send or refer anyone to you due to your extreme lack of respect and safety of fighters.There are promotions operating in New York that cover the fighters for post-fight medical care. But there are many more who don't.
No, the promoter did not have insurance for any fighters. When asked about insurance, he laughed and said, "If I bothered with insurance I'd be broke after every event."
Forget all the hours spent training in the gym and the blood, sweat and tears shed. This is the real price of competing in unregulated New York.
