Floyd Mayweather Jr.'s rematch against Manny Pacquiao appears to still be in danger of being called off despite a recent report to the contrary.

Ronda Rousey described next month's comeback bout against Gina Carano as the biggest mixed martial arts fight of all time and said it would be a pivotal moment for ​the sport.

Ronda Rousey already has her hands full with Gina Carano ahead of the pair's dual returns to MMA atop Netflix's May 16 mega-event.

"Gina is so relevant that she's the whole reason why the 145-pound division even exists; I'm so irrelevant that the only reason she has a job is because of me," Rousey shouted on the microphone.
