Josh Herdman grew up playing the Slytherin bully Gregory Goyle in the Harry Potter series. Remember him?

Now, he's an MMA fighter.

One of Draco Malfoy's right-hand men debuted in England over the weekend with a unanimous decision victory over Janusz Walachowski.

He told Chris Emmanuel of Addicted OTR that he's been "training traditional Japanese [jiu-jitsu] for nearly five years and [holds] a shodan black belt."

Don't hang your heads yet, though, muggles—Herdman isn't done with acting:

I haven't fallen out of love with [acting]. 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.

Potter vs. Herdman, anyone?
