Down-and-dirty fighting comes to the Middle East in this spectacular event staged in April 2010 on Yas Island, Abu Dhabi, in the United Arab Emirates, with Anderson Silva facing Demian Maia in a middleweight championship bout. The second main event features lightweight champion B.J. Penn vs. Frankie Edgar. Staged in a specially constructed arena within the Ferrari World theme park, UFC 112 was also the first UFC event to be held outdoors.
