On Saturday at UFC 177, Renan Barao will become the first fighter in eight months to challenge for a UFC title despite coming off a loss.

Barao rematched reigning 135-pound titleholder T.J. Dillashaw and looks to avenge his loss in May.

Dillashaw (10-2 MMA, 8-2 UFC) battered Barao (32-2 MMA, 7-1 UFC) for more than four rounds before scoring a fifth-round TKO at UFC 173. The rematch takes place a little more than three months later, and the Brazilian is coming for redemption.

The contest headlines a card that, outside of the main event, features no fighters listed in the USA TODAY Sports/MMAjunkie MMA Power Rankings. It all takes place Saturday at Sleep Train Arena in Sacramento., and airs live on pay-per-view following prelims on FOX Sports 1 and UFC Fight Pass.
