The bout is something of a crossroads for both men. At 35, Miller has guided himself into position for the biggest payday and most prominent fight of his career after low-key wins following a two-year ban for doping violations.
Dubois meanwhile is going straight back into a tough fight after being knocked out last time out when stepping up to challenge for world honours against the imperious southpaw and unified champion Oleksandr Usyk.
A loss for either man on the Day of Reckoning card will very much drop them down the heavyweight ladder and potentially leave them somewhat out in the cold.
‘Big Baby’ has been his famously chirpy self throughout the week in Saudi Arabia and, speaking to Boxing News, said he had heard whisperings from the Brit’s camp.
“People call him a two-time quitter. Third time’s gonna be a charm. There’s a lot of excuses about what went on in those two fights but I heard a lot of things about his camp, even his sparring partners been getting his back, he’s been distracted a lot.”
He then made a prediction for what would happen when the two meet in the ring.
“I didn’t pick the fight, he picked the fight, his trainer Don Charles made a bad mistake. They know something we don’t, but I tell you one thing that’s gunna happen, he’s gunna get his a** whopped, plain and simple.”
With both careers potentially on the line, it should be a hugely entertaining match-up whatever happens.
