In April, it became clear that the American Claressa Shields chose to change course and invest in an MMA career, when she signed a multi-year contract with the organization PFL (Professional Fighters League).

That after the boxing world champion won two Olympic gold medals as an amateur and played eleven undefeated matches as a professional.

- I look forward to cementing my legacy as the foremost female martial artist of all time.

It will be exciting to step into the PFL cage for the first time and show that I do not back down for any challenges.

I have already shown that I am the best boxer in the world, and now I intend to do the same with MMA, Shields said according to ESPN.

Last night, Swedish time, the MMA debut took place in Atlantic City.

A debut that ended with a victory for the American.

However, it was compatriot Brittney Elkin who had the upper hand in large parts of the match, but just over two minutes into the final round, Shields was able to win by technical knockout.

After the fight, Claressa Shields was euphoric.

- It feels like I'm dreaming.

It's crazy, she says according to ESPN.
