UFC 137: "Penn vs. Diaz" from the Mandalay Bay Events Center in Las Vegas, Nevada, has officially wrapped, which means 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 $75,000 each.

The promotion dished out its standard post-fight monetary bonuses to four out of the 22 fighters on the card, and it's probably no surprise who's leaving "Sin City" with a second sack of simoleons.

On a night that featured just one victory by way of tapout, Donald Cerrone's rear naked choke of Dennis Siver earned "Submission of the Night" honors thanks to a lack of options. Let's not sell "Cowboy" short, though. He roped in the German dynamite stick and absolutely owned him.

Who's next?

Also hauling in a wheelbarrow full of cash is Bart Palaszewski, who brought home his extra bacon by earning "Knockout of the Night" via flying flurry against the fence that Tyson Griffin had no answer for. You know, other than to fold up like a cheap lawn chair.

Finally, B.J. Penn and Nick Diaz took home "Fight of the Night" honors after their thrilling back-and-forth, war of attrition that saw the Strikeforce welterweight champion earn the biggest win of his career. Was it enough to move him back to the front of the 170-pound line, Carlos Condit be damned?

Stay tuned.

Here are the special fight bonuses for UFC 137:

Submission of the Night -- Donald Cerrone

Knockout of the Night -- Bart Palaszewski

Fight of the Night -- B.J. Penn vs. Nick Diaz

Again, each fighter received $75,000 extra for their performances in addition to their respective base salaries, which we will pass along as soon as possible.
