"I think Brock Lesnar is done. I think Brock doing TUF is one way to basically take a situation and make it win-win for him. I think Lesnar doing the show is a way to introduce Junior Dos Santos to the American fan base in the way the show does. TUF introduces "stars in the making" to the casual UFC fan and while JDS is the number one contender he still needs some help with the American fan base. So the conspiracy basically comes down to the fact that Shane Carwin has no one to fight in June. I think Brock Lesnar will walk off the TUF set and then Carwin will take his spot or Frank Mir will come in to "save the day" and fight JDS for title contention." -Roy Nelson via Bloody Elbow

UFC heavyweight contender Roy Nelson does his best Jim Marrs impersonation stating his belief that Brock Lesnar will preemptively walk off the upcoming TUF 13 show.

Nelson points to the fact that Carwin, who is said to be fighting sometime this summer, doesn't have an opponent and all of the top heavyweights are already tied up with fights or otherwise indisposed with injuries.

Nelson (15-5), is scheduled to face former UFC heavyweight champion Frank Mir at UFC 130. The girthy heavyweight is coming off of a tough one-sided decision loss to Junior dos Santos in his last outing at UFC 117 in August.
