Alistair Overeem will fight Brock Lesnar tonight (Dec. 30, 2011) in the main event of the UFC 141: "Lesnar vs. Overeem" pay-per-view (PPV) event booked for the MGM Grand Garden Arena in Las Vegas, Nevada.

And he'll be paid very handsomely in the process.

More so if he wins, which will bring him $385,713 plus a PPV bonus of $2 per purchase. Not too shabby for a debut fighter who is an unproven draw on U.S. soil.

ESPN.com has the details.

Pursuant to the terms of Overeem's UFC contract as outlined in the complaint, he is guaranteed a "bout fee" of $264,285 on Dec. 30. Should he defeat Lesnar, Overeem would receive an additional $121,428 "win bonus." Overeem is also in line to receive a $2 pay-per-view bonus per viewer, "for all revenues received by UFC-Zuffa for telecast of the Lesnar fight in the United States, Canada or over the internet in excess of $500,000."

That's not all.

Terms of the contract also guarantee Zuffa would pay Overeem $1 million spread out evenly over the first three fights of his deal, which is potentially good for up to eight bouts. Overeem is also expected to receive intellectual property payments for worldwide marketing of his likeness or image.

Why are those numbers so important?

Well, Overeem is being sued by Knock Out Investments (KOI) and Golden Glory, his former representatives, who allege that "Demolition Man" is in breach of contract. In layman's terms, he signed with UFC, got paid boku bucks, then dumped his crew and kept all the money.

"The Reem" however, paints a very different picture and has filed a suit of his own. Perhaps all the legal fees he's likely to incur will help motivate him to win tonight in "Sin City?"

Stay tuned.
