Hafthor Bjornsson and Eddie Hall are set to meet in a boxing match on September 18 in America.
The Icelandic titan, also known for playing Gregor ‘The Mountain’ Clegane in Game of Thrones, will face off with the Brit in a battle of strongmen.
In 2017, Hall was crowned World’s Strongest Man.
Bjornsson followed this up by winning that very same title in 2018.
Last year, Bjornsson broke Hall’s deadlift world record of 500 kg (1,100 lb) by deadlifting 501 kg (1,105 lb).
This has stoked a rivalry between the pair which will now be settled in the ring.
MTK Global will serve as the official boxing advisors for the event which has now been announced for September 18 in the US.
Ticket sales are set to begin on July 5.
The PPV for the fight will be broadcast via online platform CoreSports.World.
Early pricing has been announced for fans who order in advance at $9.99 (£7.99)
It has not been specified if/when this will increase in the coming months as the build-up intensifies.
When the event was first confirmed without an official date last year, Hall said: “I’m training for this fight like I trained to be the strongest man in the world, no stone unturned and anyone in my way is getting milled down.
“With the experience MTK Global [the official boxing advisers to organisers Core Sports] brings to the table, this event will be even better than it was going to be.
“As for the fight itself, I have zero doubt in my mind that cry baby Thor is getting folded in half and sent packing back to Iceland.”
Bjornsson added: “I’m very excited with MTK Global’s involvement as this is something I’ve been taking very seriously and I want others to know how serious this fight will be.
“I’ve been extremely focused and dedicated in my training as always and I am looking forward to getting in that ring.”
