Claressa Shields has vowed to become a multi-sport great as she prepares for her MMA debut with Professional Fighters League.
The 'Greatest Woman of All-Time' became the first boxer to become undisputed in two divisions in the four-belt era, and has won boxing gold medals at consecutive Olympics.
But she is planning a mixed martial arts fight under the PFL banner in June, and told Sky Sports: "I am mixing the disciplines to see what makes me comfortable in becoming a great fighter in MMA.
"It's all the same mind-set.
"Regrets? I've never regretted anything in my life. I've been making decisions for my life since I was 12 years old.
"I am a natural super-athlete and I learn things very quick. I've never had a day in training where the coach says: 'You did terribly'.
"They are amazed by how much I can consume in one day, how much I can work, work, work.
