Fresh off his deadlifting world record of 501kg at the weekend, Hafthor Bjornsson, who is best known for his role as Gregor ‘The Mountain’ Clegane from HBO’s TV series Game of Thrones, is set to face strongman rival Eddie Hall in a boxing ring in Las Vegas next year.

The match is billed as ‘The Heaviest in Boxing History’ with ‘The Mountain’ coming in at much the bigger man at 6ft9 and 425 pounds, compared to the Brit known as ‘The Beast’, who stands at 6ft2 and weighs around 361 pounds.

There has been no love loss between the two strongmen after ‘The Mountain’ broke the Brit’s deadlifting world record at the weekend.

Bjornsson said: “Eddie Hall has been running his mouth for weeks now. So Eddie, I just knocked out your record and now I’m ready to knock you out in the ring.”

Not one for backing down, ‘The Beast’ replied: “I don’t care if you’re 6ft 9in, I don’t care if you’re an actual giant. I’m going to train the hardest, do everything in my power to step in that ring and rip your head off!”

The feud between the pair has dated back to 2017 when Bjornsson claimed that Hall cheated to win the World’s Strongest Man title that year. Subsequently, ‘The Mountain’ claimed the title from Hall a year later.

Bjornsson, it turns out, is no stranger to the sport, with the 31-year-old Icelandic weightlifter seen sparring with an unnamed opponent a few years ago.

During the three minutes, despite lacking natural boxing technique, Bjornsson clearly demonstrated his punching power as he dominated his sparring opponent for much of the round.

‘The Mountain’ has also previously sparred with UFC fighter Conor McGregor, and following that session, Bjornsson claimed he could beat the Irishman in 10 seconds.

Bjornsson said: “Bring me shorts and put us in a cage and I’ll fight him.

“If I get a grab on him it would be over in 10 seconds.”

So despite the fight in Las Vegas between the pair being 16 months away, it is clear that both the ‘The Mountain’ and ‘The Beast’ will solely dedicate every possible waking moment in preparing for this World's Strongest Man grudge match.
