Joe Pyfer is out of UFC Mexico City against Kelvin Gastelum due to upset stomach. I don't think there's enough time to find a replacement. Such a letdown.
Yeah sucks.. For all we know Pyfer prolly felt the high altitude feeling different than he's used to.

For the odds the books was giving Gastelum, there was some value imho. But oh well. But that same bet in another venue will not be the same value unless it's in another high altitude venue.
Anyway here are the results.
Flyweight: Brandon Moreno def Steve Erceg
Lightweight: Manuel Torres def Drew Dober
Flyweight: Edgar Chairez def CJ Vergara
