LAS VEGAS -- If fans are thinking about bringing the spirit of the World Cup to the Ultimate Fighting Championship in the form of a vuvuzela, forget about it.

UFC president Dana White says Wednesday that vuvuzelas -- the beehive-sounding noisemakers that have become famous during soccer's biggest event -- are being banned at MGM Grand Garden Arena in Las Vegas on Saturday.

That's when heavyweight champion Brock Lesnar will fight interim belt holder Shane Carwin.

"This decision was pretty simple," White said. "Vuvuzelas make the most horrific sound I've ever heard. I'd rather let Brock punch me in the face than hear 15,000 people blow on those things.

"This is the biggest heavyweight fight we've ever done. We'll make enough noise this weekend when Brock and Shane finally step inside the Octagon."
