Roughly fuck all.
This isn't just another one of his bottle throwing antics, he's just cost at least 6 fighters their wages for Saturday night, along with however many UFC and Barclays Centre staff want to say they felt distressed by the incident.
This is gonna cost him more than a few hundred grand, it could potentially run into tens of millions of dollars when U.S. litigation culture is taken into account. Loss of future potential earnings, as well as physical and emotional harm, can get extremely expensive very quickly.
Dude better fight Mayweather and Pacquiao on the same night twice if he wants to pay his upcoming lawsuits.
