Hearn has opened talks with Wilder’s team regarding a massive heavyweight unification fight in 2018 but admits Wilder could hold more dangers due to being fulling in his prime years at 32 years old.
Joshua battled hard to overcome Klitschko at the ripe old age of 41, recovering from a knockdown and massive fatigue to eventually score a stoppage down the stretch.
As things begin to get serious between Joshua and Wilder, Hearn gave out vibes that he may want to delay the fight until at least the second half of 2018.
“Anthony likes to jump in and take fights, sometimes against advice like against Wladimir Klitschko,” Hearn explained to Sky Sports.
“As much confidence as I have in Anthony Joshua, I know the dangers of that fight. It’s the same as I felt in the Klitschko fight, but the difference in this fight is it’s two guys in their prime.
“Two young, fast, athletic punchers and that’s why it’s the biggest fight in world boxing.”
Along with his apprehension, Hearn also warned Wilder he should be careful what he wishes for.
“Deontay Wilder has been doing a lot of talking, but unfortunately he’s called the bluff of someone who loves a fight and loves to compete, and someone who loves to fight as well,” he said.
“This fight has just started to explode and it’s going to get bigger and bigger
“We have a responsibility to fight fans to make sure the best fights are made and this is the best fight in world boxing.”
