The two British rivals go head-to-head at the AO Arena in Manchester on Saturday night, but in the eyes of Hearn, both fighters are past their best despite the fan interest this contest will generate.

"Will I sit down and watch it, probably not. Of course I want to know what happens now. It’s intriguing now. Both guys are finished," Hearn told ">Seconds Out. 

"You just don’t know what’s going to happen. When I was trying to make the fight there was so much more at stake. Now, it's almost like a shake of the hands. ‘Listen, let’s just do it.’ "

When asked about whether the fight was a money grab, Hearn believes Khan and Brook are cashing in for one more big career pay day.

"I’ve been involved in money grabs,” Hearn said.

“But [Khan-Brook] is [a money grab]. It’s just the two of them going, ‘Let’s not be silly. This is massive money for the both of us. Let’s make the fight, mate.’

“But it’s still going to be a 50-50 fight. I still look at Kell and it looks like he’s training hard. Khan doesn't look particularly sharp or great, but he’s going to give it his everything.”
