UFC 109: "Relentless" from the Mandalay Bay Events Center in Las Vegas, Nevada, has officially wrapped, which means that it’s time for those select fighters who went above and beyond in their respective fights to get a little extra grease for their efforts.

To the tune of $60,000 each.

The promotion dished out its standard post-fight monetary bonuses to four out of the 22 fighters on the card. And it may not surprise you which combatants are leaving "Sin City" with a little extra green.

In addition to their base salaries, the UFC awarded middleweight competitors Chael Sonnen and Nate Marquardt "Fight of the Night" for their thrilling three rounds of action.

Unfortunately Sonnen spoiled a "Great" opportunity for Marquardt to get back into the number one contender spot with a dominating performance that saw him survive both a deep laceration and last minute submission scare.

Is he destined to meet the winner of Anderson Silva vs. Vitor Belfort later this year?

Representing the 170-pound weight class was AKA nemesis Paulo Thiago. The Brazilian supercop made "Quick" work of Mike Swick's title aspirations with his slick "Submission of the Night" that came via D'arce choke in the second round.

Also bringing home the proverbial bacon was former UFC welterweight champion Matt Serra. "The Terror" made his return to the Octagon a memorable one, turning Frank Trigg inside-out to grab "Knockout of the Night" after putting "Twinkle Toes'" on his butt in the first round.

Here are the special fight bonuses for UFC 109:

Fight of the Night — Chael Sonnen vs. Nate Marquardt
Submission of the Night — Paulo Thiago
Knockout of the Night — Matt Serra

Again, each fighter received $60,000 extra for their performances in addition to their respective base salaries, which we will pass along as soon as possible.
