Frankie Edgar has made his much-anticipated move to the featherweight division and will immediately challenge Jose Aldo for the UFC's 145-pound championship. The superfight will headline UFC 156, which takes place Saturday at the Mandalay Bay Events Center in Las Vegas.
With one of the most stacked main cards in recent memory, UFC 156 could also conceivably produce two top contenders in other divisions.
Elite heavyweight Alistair Overeem will return from suspension for a fight with Antonio Silva, while top flyweights Joseph Benavidez and Ian McCall will try to prove they are worthy of a rematch with 125-pound champion Demetrious Johnson.
As always, Bleacher Report's expert panel will predict the aforementioned fights and the rest of the bouts on the UFC 156 main card.
