Legendary Australian Muay Thai pioneer John Wayne Parr has signed with ONE Championship. Parr announced the news via his Instagram page.

“Happy to announce Johnny is back. During my last trip to Singapore Mr @yodchatri approached me to see if I’d be interested in joining the @onechampionship family. Word’s can not describe how happy I am to be back amongst it again on one of the biggest promotions in the world.”

At the age of 43, Parr brings a wealth of knowledge to the sport and it’s likely that competitors will be lining up to fight him.

Parr talked openly about his hip after retirement, which needed an extended period of time to fully recover after more than two decades of gruesome Thai training sessions and beatdowns. It now looks as if that issue has been dealt with, and the multiple-time world champion is ready to make a return to the ring he once called home.

“After some time off it has allowed my hip to recover so I can concentrate on getting fit and strong again. Life really is amazing.”

John Wayne Parr was present at the most recent ONE Championship card in Singapore, as his student Rocky Ogden was competing for the chance to earn strawweight gold. Throughout fight week the man they call “The Gunslinger” was teasing a return to the sport, regularly posting photographs in ONE Championship gloves.

Parr is just one win short of a monumental 100th career victory. His record now stands at 99 victories, 34 losses, and 1 draw.
