#4 Jarrell Miller
Next Fight: vs Johann Duhaupas on 28 April 2018
Brooklyn born 'Big Baby' Miller is another rising star of the heavyweight division who appears to be on the cusp of challenging for world honours. He is currently ranked in the top 10 heavyweights with three of the four major sanctioning bodies.
Those same three organisations each have their title belts on the line this Saturday when Parker meets Joshua in Cardiff. This makes it very likely that Miller will soon be in line to challenge whoever emerges victorious.
All he has to do is keep winning and keep knocking on the door of the heavyweight elite as he has done so far by calling out Joshua publicly, claiming he will be the one to expose the undefeated champion, and even attempting to invade the ring and confront Deontay Wilder after his victory over Luis Ortiz earlier this month.
These actions have not gone unnoticed by promoter Eddie Hearn who has claimed that should Joshua and Miller both win their upcoming bouts then a showdown in America awaits.
"Anything could happen - Jarrell Miller could be beaten [by Johann Duhaupas], we might fight Deontay Wilder next, the WBA might call their mandatory. If we box in America and it's not Wilder, Miller will be the perfect guy."
