Dana just predicted this will be the biggest event ever
"He was medically cleared, but he decided to not fight," White told hosts Kenny Florian and Daniel Cormier. "He stood to make a lot of money in this fight. The bigger issue was making weight. You lose a fighter like Jose Aldo and put Mendes in and we added to the gate. This fight is breaking every record, pre-buys on PPV, traffic on the website, it's bigger than UFC 100. This will be the biggest fight ever."
UFC 100 did 1.6 mil buys having Brock Lesnar AND GSP on the card. If 189 gets anywhere north of 1 mil buys I'd be amazed.
