Which UFC event took place in Abu Dhabi in April 2010?

UFC 112 was the UFC event that took place in Abu Dhabi in April 2010. Officially titled UFC 112: Invincible, it was held on April 10, 2010, at the Concert Arena on Yas Island.

The event was significant as the UFC's first show in the United Arab Emirates and one of its earliest major attempts to establish a presence in the Middle East. The card featured two championship bouts. Anderson Silva defended the UFC Middleweight Championship against Demian Maia, while Frankie Edgar challenged B.J. Penn for the UFC Lightweight Championship.

Edgar won the lightweight title by unanimous decision, beginning a major championship era in his career. Silva defeated Maia by decision, but the bout became controversial because Silva repeatedly taunted his opponent rather than engaging consistently. The fight went the full five rounds.

UFC 112 is easy to confuse with UFC 110, UFC 114, or UFC 120 because all were numbered events from the same period. The location and date provide the identifying clues: UFC 112 was the April 2010 Abu Dhabi card.
