Long-time Paul rival KSI has joined boxing fans in reacting to the news on social media.
He wrote: “50+ years old. No one wanted this… So sad to see man…”
Dillon Danis, who fought Paul’s older brother Logan last year, also wrote: “You’re fighting someone who was born in 1966. Have some shame.”
Former UFC champion Michael Bisping added: “You should be ashamed of yourself. And the biggest joke is you don’t even slightly realize why.”
Fans agreed, with one commenting: “Everybody involved in making this fight fight happen should go to prison.”
