Guy Fieri is using a wheelchair and crutches after his leg muscle "exploded"

Guy told Fox News Digital: "[I] slipped down a set of steps and one foot went forward and the other foot got caught on the threshold.

"So, you know, it extended me out. I looked like I was probably doing the splits, but when my right leg compressed into itself, the giveaway point, and the doctor said he's never seen - you know, in 20 years - he hasn't seen a tear in the biggest, thickest part of your quad in half. Yeah, it sucked.

"You normally tear that muscle at your tendon or the tendon tears off the bone, but this was right in the centre of the whole quad muscle and it exploded."

The 57-year-old Food Network star has been told to stay off his feet for eight weeks, and he will then wear a cast while undergoing rehab.

He said: "Eight weeks of no weight on it, crutches and a cast and then the rehab, which to me - I want to get after it as fast as possible. He's like, 'You know as much as you want to, get back to being Guy, you're going to really have to go through [it].'

"I haven't busted anything. I mean I broke it all as a kid. I broke my leg, broke my knee, broke my wrist, broke my sternum, my ribs, my tailbone. I mean, you know, name it, I broke it. But I got done doing that s***. You know, I got done with that type of behaviour long ago."

As a result, he is taking a backseat from Thanksgiving cooking, with sons Hunter, 29, and 19-year-old Ryder - who he has with wife Lori - taking charge along with Guy's nephew, though the chef will be keeping an eye on their progress.

He said: "Oh, it's going to affect it because I'm on crutches and in a wheelchair. I mean, I have to stay off it and the whole thing. I can't walk on it for eight weeks.

"So it was funny. My son, Ryder, texted me from school and he said, 'Well, I guess all the training you've given me and all the cooking I've been doing while I was at school, it was going to be my time to shine.' And I said, 'I am so happy you're asking me about this versus me telling you, you have to do it.'

"So, I got my three boys, Hunter, Ryder and Jules, and they all know how to cook. And now it's gonna be me quarterbacking from the wheelchair and telling them what to do. And we cook for about 40 people up here. So it's going to be, it's got to be an adventure."

The accident happened "right in the middle of filming" a new show, Flavor Town Food Fight, which proved tricky for producers.

He said: "We've got everybody in town and all the chefs there and 125 people on set - and everybody's ready to go - and I'm in surgery.

"So, we figured out how to pivot through it and to have some creative filming techniques. But it's been a run, and now I'm up here at the ranch, where it's always about hiking and outdoors and, you know, beautiful."
