(Don't fear the belly; fear the consequences.)

Kimbo Slice’s chances of winning season ten of “The Ultimate Fighter” just got a little worse, because according to MMA Madness former IFL heavyweight champion Roy “Big Country” Nelson joined the cast of the show, which began filming last week. Those of you didn’t watch a lick of the IFL might remember Nelson from such bad referee stand-ups/devastating knockouts as his loss to Andrei Arlovski on the same EliteXC card that produced the StandGate incident. After that Nelson lost a very close decision against Jeff Monson at March Badness, bringing his pro record to 13-4.

Also appearing in this season will be gangly former UFC heavyweight contender Wes Sims, who’s been busy padding his record lately against no one you’ve ever heard of. The 6’10” Sims lost all three of his fights in the UFC and has been disqualified twice in his illustrious career. He also made our Best Technical Submissions list for getting choked out by Daniel Gracie, so you might say he’s a guy who people remember, though not necessarily for the best reasons.

While Sims is big and strong enough to pose problems for anyone without at least a modicum of MMA skill, it’s Nelson who is the more interesting addition to the cast. He may look like just another fat dude, but he has excellent jiu-jitsu and knockout power, while also somehow having a pretty good gas tank. Basically, he’s the kind of guy who could probably beat Kimbo without ever putting down his hoagie.

Seeing a real, experienced fighter like Nelson added to a cast that includes Slice, a few ex-NFL players, and some other as of yet unnamed guys makes you think that the UFC is serious about not giving Kimbo an easy road to the finals just for the sake of ratings. It also makes you think that a wisecracking coach like “Rampage” Jackson is going to have a lot of fun making jokes about Nelson’s doughy physique. Yep, the tenth season is really looking like it’s going to be one to remember, for one reason or another.
