The Ultimate Fighting Championship handed out $60,000 bonus checks for the top performances at UFC 109 at the Mandalay Bay Events Center on Saturday night. Matt Serra, Paulo Thiago, Chael Sonnen and Nate Marquardt all earned bonus money.

Fight of the Night honors went to the middleweight contender bout between Nate Marquardt and Chael Sonnen. Sonnen dominated the better part of the fight with superior wresting, although Marquardt came on in the final round before falling short on the judges’ scorecards.

The Knockout of the Night went to former UFC welterweight titleholder Matt Serra who caught Frank Trigg with a right hand, sending him to the canvas. He finished off the former MMAWeekly Radio co-host with strikes on the ground half way through the first round.

Paulo Thiago scored Submission of the Night with his D’arce choke of Mike Swick. They fought a close first round, but a counter punch in the second sent Swick to the canvas where the Brazilian was able to finish with the choke.

Total bonus money paid out for UFC 109 was $240,000.
