One of the biggest rematches in UFC history takes place tonight, and though UFC 200 was expected to be the promotion’s biggest event of all time, UFC 202 might just trump it.

A welterweight rematch of one of the most memorable fights in UFC history tops the event, which takes place at T-Mobile Arena in Las Vegas with a main card on pay-per-view following prelims on FS1 and UFC Fight Pass. Reigning featherweight titleholder Conor McGregor (19-3 MMA, 7-1 UFC) will once again move up in weight in hopes of avenging his lone octagon defeat, a second-round submission to “The Ultimate Fighter 5” winner Nate Diaz (19-10 MMA, 14-8 UFC) at UFC 196 in March.

Both men are among the most accomplished fighters on the UFC roster, and the next chapter of their heated rivalry will unfold Saturday in “Sin City.”
