The main event between Ortiz and Sonnen saw the most viewers with 1.85 million viewers, making it the fourth most watched Bellator fight in the promotion's history. Ortiz submitted Sonnen in the first round of their fight with a rear-naked choke. Following the win, Ortiz retired from MMA. After the fight, Sonnen said he will compete again for Bellator and is interested in a fight with Wanderlei Silva. If the two were to fight, it will be interesting to see how many viewers it can pull compared the other most watched fights in Bellator history.
