As the final horn sounded to end the event, it was obvious that the brothers Pettis had a great enjoyed night at UFC 181 yesterday in Las Vegas.

The elder Pettis, Anthony, successfully defended his UFC Lightweight Championship with a second round submission victory over Gilbert Melendez in the co-main event. The defeat marked the first loss inside the distance in Melendez’s storied career, which includes championship runs in WEC, Shooto, and Strikeforce.

The younger Pettis, Sergio, earned an important win on the undercard. His opponent, Matt Hobar, knocked the 21 year old to the canvas early in the fight, but Pettis came back to dominate — keeping the momentum going on his young career.

But the night got even sweeter for the brothers afterwards — as it was announced they were among the winners of the promotion’s post-fight bonuses.

Anthony received “Performance of the Night” for his historic win. Sergio and opponent Hobar received “Fight of the Night” honors. Each nets $50,000.

Sergio also received “Fight of the Night” honors earlier this year in a losing effort against Alex Caceres. He is the first fighter to be awarded “Fight of the Night” twice in the same year since Joe Lauzon in 2012, who accomplished the same feat in 2010.

The final post-fight bonus was awarded Josh Samman, who also received “Performance of the Night” honors. Samman was dominated by the ground-and-pound attack of opponent Eddie Gordon in his undercard bout, when he landed a spectacular round kick to the head — knocking Gordon out cold.
