For just the second time in UFC history, the organization saw two undisputed championship belts change hands in one night. UFC 185 featured a pair of title bouts at the top of the bill, and in an unlikely outcome, two new champs were crowned.

Rafael dos Anjos (24-7 MMA, 13-5 UFC) dominated Anthony Pettis (18-3 MMA, 5-2 UFC) to capture the lightweight belt in the main event while Joanna Jedrzejczyk (9-0 MMA, 3-0 UFC) mauled Carla Esparza (10-3 MMA, 1-1 UFC) to take the helm in the women’s strawweight division.

Both American titleholders were favored to retain, but it wasn’t meant to be as Dallas’ American Airlines Arena was the site of two upsets. The start of two new title reigns wasn’t the only notable occurrence to come out of the pay-per-view event. Check out 55 post-fight facts to come out of UFC 185.
