HAFTHOR BJORNSSON admitted he was “humbled quite badly” during a grapple with Gordon Ryan.
Bjornsson, who weighed over 23 STONE in his last boxing match, got taken to school by jiu-jitsu specialist Ryan, who is only 15 stone.
The Game of Thrones star posted: “Literally went against the best and got humbled quite badly.
“@martinslciis and I got the opportunity to meet up with @gordonlovesjiujitsu while he was doing his last workout before he competes tomorrow.
“I love trying out new sport and what a pleasure it was. Excited to watch Gordon crush his opponent tomorrow! This guy is next level!”
Ryan, 27, to his credit is a Brazilian jiu-jitsu 1st degree black belt and world champion competitor.
He responded to Bjornsson: “This was such a blast. Can’t wait to attempt to lift your warm up weight one day.”
The super-heavyweight – who played The Mountain in Game of Thrones – is no stranger to combat.
Bjornsson – known as Thor – swapped the world of strongman for a short stint in boxing.
And after three warm-up bouts, he faced rival Eddie Hall, 34, in what was billed The Heaviest Boxing Match in History.
Bjornsson, 34, won on points in Dubai in March and was in talks for an exhibition with heavyweight champion Tyson Fury, 34.
But after negotiations collapsed, Thor hung up his gloves and retired from boxing.
He said: “I’ll admit there was a time when there was talks between Tyson Fury and I, his team and my team, there was build-up but that never went through.
“Now I’ve made a hard decision and the reason why it took me so long to make this video was because this is actually a very difficult thing to talk about.
“I’ve made a decision to move on from boxing, to not compete in boxing again, to say goodbye to boxing and just not fight again.
“I had a good run, I did it for two-and-a-half years. It was nice to do so, because when I first started I had a lot of people not believing in me.”
