Before his second consecutive headlining bout at UFC Fight Night 127, watch Fabricio Werdum become the undisputed heavyweight champion with a submission win over Cain Velasquez . The title-unifying bout between Werdum (23-7-1 MMA, 11-4 UFC) and Velasquez (14-2 MMA, 12-2 UFC) served as the headliner for UFC 188, which took place June 13, 2015, at Mexico City Arena in Mexico City. Werdum earned his shot at Velasquez after claiming the interim title with a TKO win over Mark Hunt at UFC 180, which originally was to serve as the date for Velasquez-Werdum until Velasquez withdrew with a knee injury. Velasquez claimed UFC heavyweight gold for the second time in December 2012 and defended the belt twice before facing Werdum
