For a few days, this event location was in jeopardy because there are still no regulations in place to promote the sport professionally within Vancouver and Cincinnati was rumoured to be a possible location for moving this event. However, the problems were resolved and Dana White confirmed that the show will be going ahead in Vancouver on the scheduled date.
The main event was tentatively set to be a third bout featuring Ultimate Fighter coaches and former UFC Light Heayvweight Champions Chuck Liddell and Tito Ortiz. In March, rumours began to circulate that Rich Franklin would replace Ortiz as Liddell's opponent, after Ortiz had supposedly withdrawn from the fight.
However, Dana White denied this via his Twitter account on March 13th, 2010, noting that Liddell vs. Ortiz was still set to be the main event. Then, after the announcement, Ortiz had to withdraw from the match due neck surgery. It is confirmed that Franklin will face Liddell At 115.
Despite confirming Liddell/Ortiz 3 would in fact be the main event for the card, the main event was confirmed on April 12 as Liddell vs. Franklin.
The on-again, off-again rematch between Thiago Alves and Jon Fitch, first scheduled for UFC 107 then UFC 111 and then UFC 115 has been moved again, to UFC 117.
Recently, the Ben Rothwell vs. Gilbert Yvel fight replaced Tyson Griffin vs. Evan Dunham on the main card. Griffin vs. Dunham will now be shown on the preliminaries aired on Spike TV.
Just like UFC 111 in March, UFC 115 will be shown in Movie Theatres around the United States by NCM Fathom.
