The 29-year-old featherweight was rushed to hospital in May 2024 with agonising pain caused by a twisted bowel and though it took him some time to recover, he didn’t find the process “hard”.
He told Boxing News magazine: “This is going to sound like a lie but it wasn’t that hard for me.
“I never, ever got down about it.
“I have been boxing my whole life. As soon as that happened, I had 12 weeks where I was just a partner and a dad and that was it.
“I loved every minute of it. We got a camper van, I got my dog, we cut about and seen Scotland.”
And Nathaniel threw himself into getting fit again as soon as he was able to.
He said: “As soon as I was on my feet again, I was running. I’d done ultra marathons, and as soon as I could do that, I was doing 100-mile cycles.
“As soon as I got past that stage of, ‘OK, I’m fit enough now to go back in the gym’, I was back in the gym.”
The boxer now has his sights set on fighting in America.
He said: “The guy I’m always associated with is [WBA champion] Nick Ball and it’s just because it’s an all-UK thing.
“We’ve meant to have been there before. It never happened, it’s been toyed with.
“So, that’s the guy I’m associated with. But if I had to choose, it would be for the WBC title.
“Get myself to America, get a big fight there – that’s the dream.”
