Takeya Mizugaki
After the announcement that Weidman/Machida bout had been moved, a Bantamweight Championship bout between Renan Barão and Raphael Assunção was targeted as the event headliner. However, Assunção opted to decline the bout as a rib injury sustained in his last bout at UFC 170 had not healed enough to resume the proper training in advance of the event. Barão instead fought T.J. Dillashaw in the main event. As a result, Dillashaw's original opponent at the event, Takeya Mizugaki, faced Francisco Rivera.
