UFC 139: Shogun vs. Henderson was a mixed martial arts event organized by the Ultimate Fighting Championship on November 19, 2011, at the HP Pavilion in San Jose, California. This marked the UFC’s debut in San Jose, a city known as the traditional home and main venue for Strikeforce events. Initially, UFC Heavyweight Champion Cain Velasquez was set to defend his title against Junior dos Santos at this event. However, on September 2, 2011, it was announced that this fight would be shifted to the first-ever UFC on Fox event. Vitor Belfort was initially considered for a fight against Cung Le at UFC 139, but he was later replaced by Wanderlei Silva. Dana White stated that the victor of the main event between Rua and Henderson would likely earn a chance to compete for the Light Heavyweight title.
