The UFC’s first pay-per-view in Brazil since August 2013 takes place Saturday as UFC 179 heads to Maracanazinho Gymnasium in Rio de Janeiro.

The first championship rematch in UFC featherweight history headlines the event as longtime titleholder Jose Aldo (24-1 MMA, 6-0 UFC) and No. 1 contender Chad Mendes (16-1 MMA, 7-1 UFC) meet for the second time.

Neither fighter has participated in a rematch during his career. After Aldo knocked out Mendes in an otherwise-competitive January 2012 bout at UFC 142, both men will need to make adjustments the second time around.

Aldo and Mendes are two of the most accomplished 145-pound fighters in MMA history, and they own arguably the best resumes of anyone in the division.
