On October 28, 2010, UFC president Dana White announced that World Extreme Cagefighting (WEC) would merge with the UFC and that WEC Featherweight Champion Jose Aldo would be promoted to UFC Featherweight Champion. Josh Grispi was pulled from a planned WEC 52 bout with Erik Koch to challenge Aldo for the Featherweight title at this event. However, Aldo was later forced off the card with an injury. Grispi remained on the card and fought Dustin Poirier.
UFC 125 preliminary fights were shown live for the first time on Ion Television in the United States. The preliminary fights were shown live in the United Kingdom on ESPN, Rogers Sportsnet in Canada and Fuel TV in Australia.
