The boxing match between strongman Hafthor Bjornsson and YouTuber Devon Larratt promises to be a great night of entertainment.
Bjornsson, 32, is arguably the strongest man in the world (along with Eddie Hall) and one of the most recognisable faces on the planet.
He's must-see TV no matter what he does, purely because you never quite know what to expect from the man known only as 'The Mountain' from Game of Thrones.
Larratt is a significant underdog but he's a former paratrooper who claims he is not taking this lightly in the slightest.
And if that isn't enough to whet your appetite, there's also a handful of other intriguing matchups on the undercard to satisfy your curiosity.
In the co-main event, Josh Bridges will battle fellow CrossFit rival Jacob Heppner for the ultimate bragging rights.
Elsewhere on the undercard, Netherlands hot prospect Anthony de Bruijn will be hunting another knockout when he walks to the ring against Georgian journeyman Giorgi Gachechiladze.
Martin Bakolie and Haruna Osumanu also clash in a battle of heavyweight bruisers and Stefanie Cohen faces Marcela Nieto in a featherweight four-rounder.
UPDATE September 15th: Bjornsson has shown off his incredible body transformation ahead of his professional debut
Bjornsson has predicted he will knock out Larratt in the first round of their pro bout on Saturday night.
UPDATE September 7th: Bjornsson has thrown down the gauntlet to Mike Tyson and challenged him to a boxing match.
