UFC 118: Edgar vs. Penn 2 was a mixed martial arts event held by the Ultimate Fighting Championship on August 28, 2010 at the TD Garden in Boston, Massachusetts, United States. The third UFC Fan Expo coincided with the event.  This event was the first the UFC held in Massachusetts.
Nate Marquardt and Alessio Sakara were originally set to face each other at UFC 116, but the fight was cancelled due to the death of Sakara's father. On July 23, Sakara's original opponent, Jorge Rivera suffered a broken arm in training and was replaced by Gerald Harris. On August 5, Sakara (who was back on the card) then bowed out due to an unknown injury and was replaced by Joe Vedepo. On August 18, it was announced that the Harris/Vedepo bout had been scrapped altogether.
A bout between Nate Marquardt and Rousimar Palhares was moved to UFC Fight Night 22 and promoted to the new main event. The original Fight Night main event was scheduled to be Demian Maia vs. Alan Belcher, however, Belcher had to withdraw due to an injured retina. As a result of this, Maia was moved to this card and fought Mario Miranda.
On August 5, it was announced that Terry Etim had suffered a broken rib in training and was pulling out of his bout with Joe Lauzon. Etim was replaced by former UFC and TUF veteran Gabe Ruediger. 
On August 25, Dana White announced that the winner of the Florian vs. Maynard fight would be guaranteed the next shot at the lightweight title.
