The Octagon heads to Brazil Saturday night for UFC 212, as Jose Aldo and Max Holloway meet to unify the featherweight title.
Aldo was awarded the belt after the promotion stripped Conor McGregor, having won the interim title over Frankie Edgar last year. Holloway won his interim belt with a victory vs. Anthony Pettis.
Top strawweight contenders Claudia Gadelha and Karolina Kowalkiewicz meet in the co-main event, while Vitor Belfort takes on Nate Marquardt in a featured attraction.
Anderson Silva was scheduled to fight Kelvin Gastelum, but Gastelum was suspended and Silva refused several other opponents.
