UFC 188: Velasquez vs. Werdum was live from the Arena Ciudad de México as the UFC made its second appearance in Mexico City, Mexico on June 13, 2015.
The main event was a UFC Heavyweight Championship unification bout as the champion Cain Velasquez took on the Interim UFC Heavyweight Champion Fabrício Werdum. The co-main event was a fight that fans have been yearning for, for some time as former Strikeforce Lightweight Champion Gilbert Melendez took on former Bellator Lightweight Champion Eddie Alvarez.
Just like at every event, UFC 188 saw a bunch of fighters come out victorious and take a step forward in their career, whereas others were unsuccessful and have to take a step back for the time being.
