Supremely confident Shields, who has said she is the second-greatest boxer to Muhammad Ali and won praise from UFC star Conor McGregor for her move to MMA, faces Elkin, who has won three and lost six of her professional fights, in New Jersey on June 10.

After catching wind of what she perceived as her opponent promising a quick, humbling finish when they meet, the ex-undisputed light-middleweight champion gave her own thoughts on the bout.

"Everybody wants the knockout, everyone wants the stoppages – but for me, I just really want the experience," Shields told TMZ.

"I want to get in there and get out as quick as possible, I'm fine with that. But if I have to go for 15 minutes and have an all-out war with Brittney Elkin, I'm fine with that.

"I saw an interview where Brittney Elkin said she wants to make me a 15-second highlight reel. Like she wants to go in there and knock me out in 15 seconds. And I was just thinking to myself, 'B*tch, in your dreams. In your wildest dreams.

"I wasn’t going to talk trash for the fight because I feel like I don't have that right because it's my first fight in MMA," she admitted – but still that didn't stop the opinionated pugilist from doing just that.
