A meeting of “Cowboy” vs. “Cowboy” will now headline UFC Fight Nigh 83, as Alex Oliveira replaces Tim Means vs. Donald Cerrone.

Set for Pittsburgh on February 21, the event will air on FOX Sports live.

Oliveira (14-2-1) has scored three straight wins, knocking out Piotr Hallmann last November. He lost his Octagon debut last May to Gilbert Burns, but has rebounded with wins over K.J. Noons, Joe Merritt and Hallmann.

Cerrone (28-7) saw his eight-fight win streak come to a screeching halt at the hands of UFC lightweight champion Rafael dos Anjos in December. Dos Anjos earned a first round TKO victory, marking just the second time Cerrone had been stopped via strikes.

Both fighters are nicknamed “Cowboy,” with Oliveira earning his from his rodeo bullriding days.
