We all remember him as Draco Malfoy's aide Gregory Goyle in the Harry Potter series, but now the actor has taken on a different career.

Josh Herdman looked completely different as he made his debut in the fighting ring this week; winning his first match against Polish fighter Janusz Walachowski in London.

The 28-year-old actor starred in all eight films but now trains in mixed martial arts. 

He told The Mirror: “I’ve been training traditional Japanese jujitsu for nearly five years and hold a shodan black belt."

“It’s raw, exciting and unpredictable. I find it more interesting than boxing although I appreciate the beauty and art in boxing. It also made sense to move onto MMA because of my jujitsu training.”

However, the former HP star also admitted that he hasn't given up on acting just yet.

“I haven’t fallen out of love with it, I still have an agent and still go for auditions. It’s just a little bit like playing the lottery for a living.

“I don’t see it so much as a career change, I am passionate about both acting and fighting," he added.
