The rest of the UFC on FOX 29 main card promises excitement as well. Rising middleweight star Israel Adesanya faces a tough test in Marvin Vettori, as well as a pivotal strawweight bout between Michelle Waterson vs. Cortney Casey.

Carlos Condit also returns at UFC on FOX 29, although it won’t be against Matt Brown, much to the chagrin of many fans that had been anticipating the welterweight showdown for years. Brown had to drop out because of a knee injury, but there was no drop-off in his replacement, as Alex “Cowboy” Oliveira stepped in to keep Condit on the card.
