History will be made at the Principality Stadium on March 31 when two reigning world heavyweight champions face off in Britain for the very first time.
Anthony Joshua's latest challenge comes in the shape of New Zealander Joseph Parker, who is also unbeaten in his professional career with 18 of his 24 victories coming via knockout.
Joshua has won all 20 of his bouts inside the distance, and the unification fight will be the first time that two undefeated reigning world heavyweight champions will have met in the ring.
Joshua is the clear bookies' favourite to extend his unblemished record as he looks to add Parker's WBO title to his WBA, IBF and IBO belts, which are also on the line.
