Before joining WWE, Sheamus fought on the European circuit, where he had several successes, winning the International Heavyweight Championship twice during his tenure in Irish Whip Wrestling (IWW). In the last few months of 2017, it was revealed that he is suffering from a spinal stenosis of the lumbar spine (a pathology affecting the spine that has already affected many wrestlers in the past), and this could slow down the continuation of his career.
After becoming part of the WWE main roster in 2009, he would go on to be a four-time world champion, having held the WWE (World Heavyweight) Championship three times and WWE's World Heavyweight Championship once. In a long interview with CTV in Vancouver, he revealed when he knew this is what he wanted to do: “So, the first guy I ever watched was Macho Man Randy Savage, his feud with George The Animal Steel, and it was on Sky One when I was in Dublin as a kid.
I remember watching it when I was a kid, and I was just blown away from it. I grew up with World of Sport Wrestling with Fit Finlay and William Regal, Big Daddy, and Giant Haystacks. And I remember when I just saw these WWE — WWF at the time – WWE Superstars, I was just blown away.
This is crazy. This is like real-life superheroes. It’s insane”.
