Tyson Fury and Deontay Wilder will renew their rivalry in tonight''s trilogy bout dubbed 'Once and For All', which will culminate one of boxing's fiercest battles in recent years.
As well as bringing an end to the pair's fighting history, the fight will also result in a bumper payday for two-time heavyweight world champion Fury.
In December 2018, the two faced off for the first time in Los Angeles in a bout that ended as a controversial draw - sowing the seeds for future bouts.
The California State Athletic Commission shows that Fury made $3m (£2.17m) from the first fight, which is peanuts compared to his future earnings from the rivalry.
'Unfinished Business', the second fight between the pair in February 2020, saw Fury knock out his opponent and earn a cool $26m (£18.84m) from the bout in Nevada.
That saw the Gypsy King's annual earnings rise above $50m (£36.2m), which put him 11th in Forbes' 2020 rankings of the highest earners in sport.
Fury returns to Las Vegas for the trilogy bout and will take a 60% split of the Pay-Per-View share, equating to around $30m (£21.74m)
That's a six-time increase on the earnings he got for his initial bout with Wilder.
