Frankie Muniz suffers freak backyard accident that sidelines NASCAR career for several weeks

"In hindsight, a taller ladder would've been smarter. While I'm gutted to miss the races, I'm grateful it wasn't worse," he continued. "I feel for my team, who've poured their hearts into this season, and I'm thankful for @FordPerformance and their unwavering support. The doctor estimates a 6-8 week recovery, so I'll be back in the driver's seat as soon as I'm cleared."

A representative for Muniz did not immediately respond to Fox News Digital's request for comment. 

The fracture comes nearly a year after Muniz suffered multiple injuries from a multi-vehicle collision while competing in the NASCAR Craftsman Truck Series in Avondale, Arizona.

After wrapping up the hit sitcom "Malcolm in the Middle" in 2006, Muniz took a hiatus from acting to focus on professional race car driving - a decision he's never looked back on. 

"As an actor, like, I've been fortunate to do a lot of great things and people tell me, 'I love your show, or I love this or love that,' but, you know, it's all based on opinion," he told Fox News Digital last year. "I could show up to work as an actor and dedicate my life to the role and feel like I did the best job ever. And then people see it and go, 'Yeah, it was OK. I didn't like it.' Where, as a race car driver, it's not subjective. It's in black and white. You either win and you're the fastest or you're slow."

"I was really kind of thrown off the deep end, but that's how I like to do things," Muniz added about his career shift. "When I do something, I like to commit fully, right? I mean, people go, 'What are your hobbies?' I don't have hobbies. I want to be the best at whatever it is I do. And if I can't dedicate the time and effort to do that, I just won't do it. I don't want to be mediocre. That's not fun."

Last year, Muniz appeared on "Fox & Friends" to reveal his decision to move to racing full-time in the NASCAR Craftsman Truck Series.

"I can't believe it, it's a dream come true," he said. "It's something that I've always wanted to do, and the fact that I actually get to announce that I'm doing it full-time next year, I'm thrilled. I can't wait."
