Aaron Riley scored a convincing unanimous decision over Shane Nelson in a fight that was bumped to the main card because the preliminary bouts ran so long.
For Riley, the victory avenged a loss to Nelson in March. The rematch was scheduled because the first meeting ended with a controversial stoppage.
The fight drew the loudest cheers of the fight, but it had nothing to do with the action in the cage.
After the first round, Shane Victorino of the Philadelphia Phillies was shown on the video board. Victorino had just arrived in his seat after getting two hits in the Phillies' 6-4 loss to Florida just across the parking lot at Citizens Bank Park. Teammate Jayson Werth joined him moments later and was also cheered loudly when he was put on the screen after the second round.
The crowd was also treated to a slugfest in the stands. A large brawl broke out and drew the attention of the nearly 18,000 people in attendance. It lasted several minutes before security was able to clear it all up.
