In March 2023 Joyce was the most dangerous and avoided contender in heavyweight boxing.<\/p>\n
He had great wins over Daniel Dubois, Carlos Takam, Christian Hammer and Parker and people were finding ways not to fight the ‘Juggernaut’, tying themselves up in other bouts.<\/p>\n
Then came the two devastating knockout defeats against Zhilei Zhang, which took me by surprise. I thought Joyce would win the first one, then I thought he would correct his mistakes and adjust in the rematch.<\/p>\n
If Joyce loses to Chisora – which would not be a shock – it puts him in a really bad position.<\/p>\n
That would be three defeats in his past four fights and he will be moving further away from world title contention.<\/p>\n
He will then have to make a decision: does he stick around and become a measuring stick for the young heavyweights out there, those clamouring to have him as a scalp on their record?<\/p>\n
That is no way for an Olympic silver medallist to see out his career.<\/p>\n
So there is a level of desperation for both Joyce and Chisora. It will be attritional and gruelling – and someone will be heartbroken.<\/p>\n
I am convinced we will know quite early on in this fight – within a minute – how the result will go and which boxer has the most left in his tank.<\/p>\n
