UFC 323 Results: Tatsuro Taira TKO’s Brandon Moreno (Video)

We have you covered for all of tonight’s UFC 323 results, including the men’s flyweight matchup between Brandon Moreno and Tatsuro Taira.

Moreno (23-9-2 MMA) will enter the contest on a two-fight winning streak, this after scoring back-to-back decision victories over Steve Erceg and Amir Albazi in his most recent Octagon appearances. The former flyweight kingpin has gone 3-2 over his past five fights overall.

Meanwhile, Tatsuro Taira (18-1 MMA) was most previously seen in action at August’s UFC Vegas 108 event, where he scored a second-round submission victory over Park Hyun-sung. Prior to that triumph, the Japanese standout was coming off the first loss of his professional career, which he suffered to Brandon Royval by way of split decision.
