CBS again will bring mixed martial arts to prime-time network television on July 26 with a card from Stockton, Calif.

EliteXC middleweight champion "Ruthless" Robbie Lawler and Scott "Hands of Steel" Smith will clash in an eagerly awaited rematch in the main event.

In a second world title fight, Jake Shields and Nick Thompson will collide for the vacant EliteXC 170-pound belt. Both fighters are on a roll -- Shields has won nine in a row; Thompson won 12 straight fights and 21 of 22. Shields hasn’t lost in more than three years, Thompson in more than two.

The world title fights are scheduled for five, five-minute rounds.

With a likely grudge rematch against EliteXC lightweight champion K.J. Noons hanging in the balance, hometown hero Nick Diaz will seek his third victory in three months when he faces Thomas "Wildman" Denny in one of the two, three-round, five-minute scraps.
