HSBC Arena in Rio de Jenairo, Brazil is hosting tonight's fiesta. The pay-per-view broadcast airs live in North America at 10PM ET/7PM PT. Featherweight king Jose Aldo puts his crown on the line against Chad Mendes in Saturday's featured attraction.

RIO DE JANEIRO – Understandably, Chad Mendes was irritated by the suggestion that he isn't ready to fight UFC featherweight champ Jose Aldo. But the owner of that suggestion, Gray Maynard, said he isn't out to get the featherweight challenger.

The event is headlined by Jose Aldo's third UFC Featherweight title defense as Chad Mendes is looking to earn the title. The co-main event features Anthony Johnson making his middleweight debut against Brazilian legend Vitor Belfort.
