Main cardHeavyweight bout: Brendan Schaub vs. Gabriel GonzagaLight Heavyweight bout: Tito Ortiz vs. Matt HamillWelterweight bout: Diego Sanchez vs. Paulo ThiagoWelterweight bout: Jake Shields vs. Martin KampmannHeavyweight Championship bout: Brock Lesnar (c) vs Cain VelasquezThe Tito Ortiz vs Matt Hamill fight is interesting because Tito was Matt's coach on the Ultimate Fighter reality show. Tito is a good wrestler but is nearing the end of his career while Hamill is also a good wrestler with ever improving standup. He really seemed to look up to Tito while on the show, so will mental games play a factor?? (side note: Matt Hamill is legally deaf...but hasn't slowed him down one bit)Jake Shields vs martin Kampmann...both really well rounded fighters, slight edge going to Sheilds, but this is his first UFC fight (former champ in Strikeforce, another promotion) so the "1st time UFC jitters" could play a role.Brock Lesnar vs Cain Velasquez, 2 talented heavyweights, Cain being the better striker and also a great wrestler. Brock comes from the WWE so his smack talk is great, but he has proven to back it up. Could be anyones game but I give a slight edge to Brock because of his size.
