HAFTHOR BJORNSSON suffered a horrific torn pectoral muscle during a mammoth bench press attempt.
The Icelandic giant recently returned to the powerlifting world following two years off to pursue boxing.
Bjornsson - who is best known for his role as The Mountain in the hit TV show Game of Thrones - resumed the insane diet and training regimes he used during his time competing in Strongman and started putting up big numbers.
Thor recently revealed he'd set his signs on breaking the All-Time Raw W/Wraps World Record Total by year's end.
But a torn left pectoral muscle has seemingly laid waste to the plans.
The 34-year-old's left pec ripped off the bone as he attempted to bench press a personal best of 252.5kg during a competition at his Thor Power Gym.

The muscle tore as the man mountain lowered the weight to his chest and made a sickening noise.
Bjornsson immediately shrieked in agony before his spotters jumped in an lifted the bar off his chest.
He lay on the bench in shock as he processed the injury, which is already the talk of the powerlifting world.
One powerlifting fan said: "He was putting up some solid number it’s such a shame.

"Wishing him a quick and full recovery."
Another said: "Scott Mendelson had a nasty pec tear and still came back to set records.
"Let's hope Thor recovers just as well."
And another said: "Poor guy. I remember hearing that noise when I tore my pec. Think I’ll not bench for awhile."
One remarked: "Oh you heard that!"
Another chimed in: "Zero chance of breaking the ATWR this year now."
Bjornsson has yet to break his silence on the sickening injury, although he shared an Instagram story featuring an image of his left arm in a sling.
Bjornsson - who battered bitter rival Eddie Hall in the boxing match last March - announced his intention to return to competitive powerlifting last month.
In a video on his YouTube channel, the Icelander said: “I competed for two years off.
"I worked my a** off, but I didn’t feel the same passion for boxing, as I had for Strongman.

“When I did Strongman training it never felt like a job.
"It felt like me just hanging out with the boys or having fun, whereas in boxing every single day felt like work.”
