UFC President Dana White noted on UFC's website, "Music is one of the things that makes the UFC experience so exciting, and I've always been a big fan of Limp Bizkit, so we are excited to have the group perform at UFC 100 event weekend."
Members of Limp Bizkit, reportedly including lead singer Fred Durst, will also sign autographs at the UFC Fan Expo, which is slated for July 10-11 at Mandalay Bay. The expo includes everything from a trade and exhibition show to UFC Hall of Fame inductions, to an official Grapplers Quest event. Limp Bizkit will sign autographs from 2-3 p.m. on the day of the concert.
UFC 100 is already sold out.
