Demetrious Johnson Prepared to 'Put on a Show' in U.S. Return

Demetrious Johnson fought 34 fights before suffering his first knockout.

That KO was suffered in a ONE Championship flyweight title bout in April 2021, when Adriano Moraes drilled him with a vicious knee.

“The longer you do this, the more likely it is you’re going to get knocked out,” Johnson says. “S--- happens. I’m not worried about it. I know how good I am.”
