Sherdog is reporting some tragic news today with the confirmation that Dave Legeno, known to Harry Potter fans as the final three films' Fenrir Greyback, has died at age 50.
Dubbed "The Enforcer," Legeno's MMA career hit a high in 2006 when he defeated both Kimo Leopoldo (via submission) and Dan Severn (via technical knockout). In addition to his work in the Harry Potter franchise, Legeno made a number of appearances on the big screen, including in Guy Ritchie's Snatch and in Christopher Nolan's Batman Begins.
No official cause of death has been reported, but, according to an official statement from the Inyo County Sheriff’s Department, it is believed that Legeno died of heart-related issues. His body was discovered by a hiking group in Death Valley, California, but no foul play is suspected.
