Three division world champion Claressa Shields (11-0), 26-years-old, will make her MMA debut next month for PFL.

Shields will face Brittney Elkin on June 10 in Atlantic City.

The two-time Olympic gold medal winner is not looking to make any mistakes in the cage - like chasing a knockout victory.

"Everybody wants the knockout, everyone wants the stoppages, but for me, I just really want the experience," Claressa said to TMZ Sports.

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

However, the undisputed champion at junior middleweight has sent a a very firm warning to Elkin (3-6 in MMA) over her recent trash talking.

During a recent interview, Elkin promised to end Shields' transition to MMA in 15 seconds.

“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, 'Bitch in your dreams. In your wildest dreams.'

"I wasn’t gonna talk trash for the fight because I feel like I don't have that right because it's my first fight in MMA."

Shields has been training at Jackson Wink in New Mexico -- one of the most famous MMA gyms in the world -- which happens to be where UFC superstars Jon Jones and Holly Holm train.

“I’ve actually spent hours working with Jon. One of the most strategic people I’ve been able to work with in MMA thus far. Like Holly is very strategic too, but she’s super energetic,” Shields said.

Holm is also a former world champion in boxing and made a full-time transition to MMA back in 2013.
