UFC Vegas 89 bonuses: Andre Lima bags never-seen-before "BOTN," prelims fight wins $50K for Fight of the Night 

UFC Vegas 89 concluded with a unique set of post-fight bonus awards, including a first-ever 'Bite of the Night' bonus.

The fight event saw a 13-bout fight card with a thrilling women's flyweight main event and a slate of fighters rewarded for their performances.

Rose Namajunas secured a hard-fought decision victory over Amanda Ribas in the flyweight headliner. After dominating the first two rounds, Namajunas faced a resurgent Ribas in the third. Despite a close fourth and fifth round, Namajunas prevailed on all three scorecards, earning her first professional win at flyweight.

The heavyweight co-main event saw Karl Williams outpoint Justin Tafa via unanimous decision. While wobbled by Tafa's punches on a couple of occasions, Williams controlled the wrestling throughout, securing a clear victory.

However, the night's most unconventional story belonged to Andre Lima. Lima's opponent, Igor Severino committed a foul by biting him in the second round. This resulted in Severino's disqualification and a history-making first-ever "Bite of the Night" bonus of $50,000 for Lima.

Beyond the bite, several fighters impressed throughout the evening, earning themselves a share of the more traditional performance-based bonuses.

Four fighters walked away with an additional $50,000 for their victories:
