The Octagon remained in Nevada for tonight’s UFC Vegas 55 event, an eleven-bout fight card headlined by Holly Holm vs. Ketlen Vieira.

The highly anticipated women’s bantamweight main event resulted in a back and forth twenty-five minute affair. Holly Holm found most of her success in the clinch, but even dropped Ketlen Vieira with a side kick during the fight. However, the Brazilian appeared to get off the harder blows throughout the course of the fight and that seemingly swayed two of the judges in attendance to score the bout in her favor.

The co-main event of UFC Vegas 55 featured a welterweight contest between fan favorites Michael Pereira and Santiago Ponzinibbio. The bout proved to be a thrilling back and forth affair. Michael Pereira got off to a strong start in the opening round but Santiago Ponzinibbio stormed back in round two. The third and final five minutes was an all out brawl but did not conclude in a finish. Thus we went to the judges scorecards for decision.

Following the conclusion of tonight’s event, UFC officials announced at the post-fight press conference that four fighters would be taking home performance bonuses.
