Back in June, after Rousey had comfortably dispatched her latest two UFC challengers in a combined time of 30 seconds, Shaq joked that he could last 45 seconds in a cage with her.

But the confident Rousey, who rarely doubts her ability to see off anyone in a fight, did admit that the NBA legend was probably right.

She said: ‘Yeah, you know, if a chick could last past 45 seconds, I don’t see why Shaq couldn’t.’

Rousey has a 12-0 record since making her Mixed martial arts debut in 2011, and only one of her fights has lasted past the first round.

In fact, her last three bouts have taken just 34, 14 and 16 seconds, with Sara McMann in February 2014 the most recent opponent to take her past the one-minute mark.

Basketball legend O’Neal claimed he would last at least 45 seconds in a UFC cage with Rousey

Next up, Rousey will face Holly Holm in the latest defence of her Women’s Bantamweight title in Australia in November.

A record crowd of up to 70,000 is expected for the November 15 fight at Melbourne’s Etihad Stadium.

Ahead of the bout, Rousey became the first woman in history to make the cover of Australian Men’s Fitness magazine.

She wrote on Instagram: ‘Thank you @mensfitnessau for making me the first woman on your cover!!’
