After a week off following the historic UFC 300, action inside the Octagon is back with UFC on ESPN 55 from the UFC Apex in Las Vegas.

Headlining is a five-round battle between top ten flyweights as Matheus Nicolau and Alex Perez both look to get back into the win column. Nicolau is in his first UFC main event while Perez takes this fight on short notice as an injury replacement for Manel Kape. Perez is looking to end his three-fight losing skid.

Also on the main card is a light heavyweight battle between Ryan Spann and Bogdan Guskov; a women's flyweight fight with win streaks on the line between Ariane Lipski and Karine Silva; a heavyweight bout pitting Austen Lane against the debuting Jhonata Diniz; and a featherweight bout between Jonathan Pearce and David Onama.
