British boxing fans should put aside their loyalty to Anthony Joshua and cheer on his rival, fellow world heavyweight titleholder Deontay Wilder, on Saturday.
They will not be switching allegiances from Joshua -- one of the biggest stars in British sport -- to American Wilder, who defends his WBC belt against Cuba's Luis Ortiz at the Barclays Center in Brooklyn, New York. Rather they want to see Wilder prevail in a seventh title defense and remain on course to face Joshua in the future, either late this year or in 2019.
Indeed, boxing fans the world over would find a matchup between knockout machines Joshua and Wilder an irresistible spectacle.
Joshua, 28, has knocked out all 20 of his professional opponents, while Wilder, 32, has taken out all but one of his 39 professional opponents.
Outside of the middleweight rematch between unified world titlist Gennady Golovkin and Canelo Alvarez, who fight May 5, a Joshua-Wilder rematch should be the biggest clash in boxing for this year and next.
But it is still a long way from being made.
And a defeat for either man is likely to end the exciting prospect of them fighting each other in the next 18 months.
If Miami-based Ortiz upsets the odds, the appeal for a unification fight with Joshua -- presuming he avoids an upset himself in his next fight -- would be considerably less than for Joshua-Wilder.
Both Wilder and Joshua need to keep winning if they are to meet in boxing's first world heavyweight title fight with four world titles on the line.
It would also be boxing's most significant matchup between two reigning world heavyweight titleholders since Lennox Lewis, who was born in London but moved to Canada aged 12, fought American Evander Holyfield twice in 1999.
Joshua, who has the WBA and IBF belts, will help himself to a third world title with a victory over New Zealand's WBO titleholder Joseph Parker at Cardiff's Principality Stadium on March 31.
With a win, Joshua's promoter Eddie Hearn would plan to take the 2012 Olympic gold medalist to box in America for the first time as a professional in August or September, possibly against Jarrell "Big Baby" Miller at the Barclays Center in Brooklyn.
That would increase interest in Joshua and strengthen his position at the negotiating table with Wilder. Hearn has scoffed at Wilder's insistence on a 50-50 split and argues Joshua has a larger profile so he deserves a bigger chunk of the money.
But there is still plenty of time to iron out a deal, as Joshua may be three fights away from facing Wilder.
After Parker and maybe Miller, Joshua is likely to have to beat Russia's Alexander Povetkin, No. 1 challenger with the WBA and WBO, if he wants to keep his belts intact and progress to Wilder.
That would push the fight back to 2019, meaning British fight fans will have to get used to cheering on Wilder as they wait for a fight with Joshua to get made.
Jamaica-born and London-based Dillian Whyte, whom Joshua stopped in December 2015 before he was champion, is No. 1 in the WBC rankings and may get to Wilder before Joshua does.
British fight fans would then have a difficult choice as to who they want to see winning: Wilder, in his last hurdle before a potential Joshua clash, or Whyte, who has lived in London since childhood and who has a tasty rivalry with Joshua.
