With the UFC bantamweight title bout between TJ Dillashaw and Renan Barao postponed due to a Dillashaw injury, the UFC flyweight championship fight between Demetrious Johnson and Kyoji Horiguchi has been elevated to the UFC 186 main event slot on April 25.
Moving into the co-main event position at Bell Centre in Montreal is the return of Quinton "Rampage" Jackson against Brazilian banger Fabio Maldonado, and getting a main card slot is the intriguing lightweight bout between Abel Trujillo and John Makdessi.
