From Gary Herman, CBS Sports:

"He has a contract if he wins this season," White said when asked about the money Slice will earn, "and it's bigger than everybody else's."

...
Just appearing on the program will not be an instant ticket to success for Slice. He has to win at least one fight and show that he is fully willing to "pay his dues" in the sport.
...

Now that the new season of the show is about to debut, all eyes will once again be on Kimbo Slice. Due to the ratings bonanza that will accompany his first actual UFC octagon appearance, Slice is getting what many fighters in the sport have not -- a second chance. Plus, Slice will have the advantage of not having to win the Ultimate Fighter tournament to make it to the UFC. He only has to demonstrate he can be somewhat competitive with a lower-level UFC fighter.

It's a cruel hard world out there and the reality is that Kimbo Slice is good for business. Dana White has shrewdly put himself in a no lose position by booking Kimbo on The Ultimate Fighter.  At a minimum he will get blockbuster ratings for the early episodes, the longer they can keep him from being exposed, the better. Anyone want to bet that Kimbo won't fight until the third or fourth episode of the show?

And if Kimbo manages to score a win, especially a convincing KTFO win, the Kimbo hype train will begin to choo choo down the tracks.

The UFC has shown every sign of stocking this season of TUF with the highest caliber of fighters that has been seen on the show since the fifth season. That's when they aggressively re-stocked their revived lightweight division with top talent. Those fighters have been mainstays of the 155lb division ever since, including Nate Diaz, Gray Maynard, Joe Lauzon, Cole Miller, Matt Wiman, and Rob Emerson. Sharing the greatly enlarged spotlight with Kimbo Slice could potentially make stars of several cast members.
