Antonio 'Bigfoot' Silva vs. Roy Nelson Slated for UFC 146

Antonio Silva's long-awaited Octagon debut is finally on the books.

Announced Wednesday, "Bigfoot" has agreed to face Roy "Big Country" Nelson in a heavyweight tilt at UFC 146, slated for May 26, 2012 at the MGM Grand Garden Arena in Las Vegas, NV. UFC officials confirmed the bout via Twitter.

Silva and Nelson join their heavyweight brethren on the Memorial Day weekend card, which is headlined by a mammoth title scrap between Junior dos Santos and Alistair Overeem. Notable fan-favorites Dan Hardy, Jason "Mayhem" Miller, Edson Barboza, and Diego Brandao are also among the confirmed participants.

Considered to be one of the top scores of Strikeforce's heavyweight migration, Silva (16-3) enters the UFC fresh from a roller-coaster run through the promotion's heavyweight grand prix.
