Eddie Hall revealed he has been nursing a back injury as he prepares to face Hafthor Bjornsson in September.
The former World’s Strongest Man has been training hard ahead of his clash with Thor in Florida on September 18.
Hall has lost around 39kg as part of his transformation and has regularly posted updates on his social media channels.
The Brit revealed he had a number of Platelet-rich Plasma (PRP) injections to help recover from a bad back.
The video was posted on his YouTube channel this week, but filmed before the 2021 World’s Strongest Man, which started on June 15.
He said: “Couple of weeks ago, was just doing sparring and pulled my back a little bit. It has just meant the last two weeks I’ve been nursing a bad back.
“I’ve come and seen a specialist. I’ve been here before when I detached my bicep in 2019 off the bone and I came here for a PRP injection just to help the process.
“This is my third visit now.”
Hall said he hoped he would be back to full training in the days that followed and has now started his 12-week fight camp ahead of facing the Icelandic giant.
It appears he is suffering no more ill effects from the injury, as he posted a video last week of him training with a 150kg heavy bag.
Hall and Bjornsson will settle their bitter rivalry on September 18 at the VyStar Veterans Memorial Arena in Jacksonville, Florida.
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).
