More heavyweight action is being added to UFC 137 as the undefeated Matt Mitrione takes on UFC heavyweight veteran Cheick Kongo in a battle of strikers with knockout power this October. Both men are coming off victories at UFC on Versus 4 this past June.

News of the bout was first reported by ESPN and has since been confirmed by UFC officials.

A former NFL player, Mitrione has found a home in MMA, posting five UFC victories and finishing four of them by (T)KO. He was recently victorious against Christian Morecraft, knocking him out late in the second round. “Meathead” rose to fame on The Ultimate Fighter 10, fighting on the show with no prior pro experience. Despite being portrayed as “a reality star,” he fell in love with the sport and has quickly improved under the guidance of Duke Roufus.

Kongo will be Mitrione’s toughest test to date though. The French heavyweight has been competing in the octagon since 2006 and has fought top heavyweights like Frank Mir and current UFC heavyweight champion Cain Velasquez. Kongo is coming off a stunning victory over Pat Barry, Mitrione’s teammate, where he was nearly finished in the fight but suddenly knocked out Barry with a short right uppercut. The knockout has already earned Kongo “knockout of the year” consideration.

UFC 137 is scheduled for October 29 at the Mandalay Bay in Las Vegas, Nevada. The show will be headlined by welterweight king Georges St. Pierre defending his belt against the always tough Nick Diaz. Also on the card is another heavyweight bout between Mirko Cro Cop and Roy Nelson in a “do or die” fight for both men.
