Khabib Nurmagomedov vs. Justin Gaethje is tracking to be the biggest fight in UFC history ... bigger than any Conor McGregor fight ... so says Dana White.
We just spoke with the UFC honcho who tells us the data he's looked at shows massive interest in UFC 254 -- and he's expecting to break the 2.4 million PPV buys that Conor vs. Khabib did in 2018.
"Yeah, it's trending bigger than that right now," Dana says.
White says the data doesn't always hold up -- but right now, he's pretty confident.
