Nate Diaz (13-7 MMA, 8-5 UFC, 3-5 in his last eight fights) has never displayed what you would call a muscular physique. He weighed 156 in his usual lean and trim shape. Takanori “The Fireball Kid” Gomi (32-7, one NC MMA, 1-2 UFC, 3-4 in his last seven fights) tipped the scales at 155 pounds.
Gomi refused to make eye contact with Diaz in the staredown.
With a defeat, one of these fighters faces the possibility of being let go by the UFC for the unwritten dropping-three-fights rule. Diaz is on a two-fight losing streak and is coming back down to lightweight from welterweight. Gomi is also coming off two losses, to Kenny Florian and Clay Guida.
Neither of these fighters has ever been stopped with a TKO/KO in a combined total of 59 bouts, so a knockout should not be expected. But each has been submitted before and with the kind of creative ground game possessed by Diaz, Gomi may be better off keeping the fight standing.
