Tyson Fury and Deontay Wilder will face each other again almost 15 months on from a controversial draw that left punters desperate for a re-run of their thrilling affair in Los Angeles.
Tickets in Las Vegas are exchanging hands for thousands of dollars, the fighters are volleying spiteful words at one another with gusto and pundits who have frequented Sin City more times than they care to remember have labelled the occasion a "monster".
Somewhere amid the chaos is the prize of Wilder's WBC world title. If Fury wins it, all four heavyweight belts will be shared between two British fighters - him and Anthony Joshua, who holds the IBF, WBA and WBO titles.
