Barboza vs. Gaethje

This Philadelphia card was the city’s first UFC event since UFC 133 and was headlined by Edson Barboza vs. Justin Gaethje. A planned Alexa Grasso vs. Marina Rodriguez bout was moved here, then changed again when Grasso was replaced by Jessica Aguilar. Ray Borg’s opponent changed twice and Borg missed weight, resulting in a catchweight fight. This was Gaethje's fifth fight in the UFC and already his fourth time headlining.
