EDDIE HALL revealed he has suffered a DETACHED BICEP - ruling him out of the fight against rival Hafthor Bjornsson.
The Strongman turned boxer explained how he caused the detachment by throwing a "lazy left hook" while in training on Monday.
Hall posted a video of the incident and could be seen punching the ground in frustration knowing what he had done.
But he seemed upbeat in his message to fans despite the bad news.
That is perhaps due to the fact he had a successful operation on his bicep on Thursday, with surgeons able to reattach the bicep - and Hall can already move the muscle.
He said on : "Little bit of bad news. On Monday I threw a bit of a lazy left hook in training and detached my bicep.
"Good news is I had the surgery on Thursday, it was a complete success. The bicep's reattached I'm able move it already, even after two days.
"Bad news is the fight is going to have to be delayed, it won't be going ahead on September 18.
"I'm doing everything I can to recover as quickly as I can and I'm looking forward to getting back to training. I'm most looking forward to ripping Thor's face off."
Hall, 33, also expressed his sadness at the development and expressed his empathy towards his fans, who were eager to see him in the ring.
The Brit was due to face his strongman rival in September 18 in Florida, in a fight dubbed 'The Heaviest Boxing Match in History'.

Opponent Thor also expressed his disappointment in a statement.
It reads: "Super disappointed but this is not in my hands.
"Next up is finding a new opponent so I can fight in September. I’m taking this extremely serious and I’ll be even more prepared. When Eddie is ready, I’ll be waiting."
Hall was crowned the World’s Strongest Man in 2017, with Bjornsson - who won the title in 2018 - accusing him of cheating.
Last year, Bjornsson broke Hall’s deadlift world record of 500 kg (1,100 lb) by deadlifting 501 kg (1,105 lb).
