Tim Tszyu will live out a lifelong dream and fight two-time world champion Keith "One Time" Thurman in Las Vegas in one of the biggest weekends in Australian boxing history.
Tszyu will headline the mega-money pay-per-view blockbuster in the US on March 30, star billing that not even his legendary father Kostya or four-weight world champion Jeff Fenech were afforded during their illustrious careers.
While the 29-year-old's legacy bout is a non-title showdown, victory over Thurman will set up a potentially career-defining super fight with either Terence Crawford or Errol Spence.
Tszyu's clash with Thurman, whose only ever defeat has come against the great Manny Pacquiao, at T-Mobile Arena in boxing's Sin City will be at 155-pound catch weight - one pound over his super-welterweight limit.
Team Tszyu is struggling to find opponents willing to enter the ring with the undefeated Sydney slayer who retained his WBO world title with a masterclass win over American Brian Mendoza on the Gold Coast in October.
But Tszyu (24-0, 17KOs) is prepared to move up a division to welterweight to secure the big fights he craves against the likes of pound-for-pound king Crawford (40-0, 31KOs) and fellow American Spence (28-1, 22KOs).
Adding to the occasion on the pay-per-view blockbuster, Tszyu's arch-rival and fellow Australian Michael Zerafa will take on reigning WBA middleweight champion Erislandy "The American Dream" Lara for the world title on the undercard.
And compatriot Liam Wilson (13-2, 7KOs) will square off with Mexican Oscar Valdez (31-2, 23KOs) in a super-featherweight world title eliminator in Glendale, Arizona, the night before on March 29.
Valdez and Wilson both lost to Emanuel Navarrete in world title slugfests last year.
But Wilson has since registered two decision wins over Jackson Jon England and Carlos Maria Alanis in Australia since flooring Navarrete in the fourth round last February and suffering a controversial loss to the Mexican.
