Brock Lesnar has faced some of the best heavyweight fighters in the world. The Ultimate Fighting Championship heavyweight title holder dominated seasoned veteran Heath Herring and put away former UFC champions Randy Couture and Frank Mir. On Saturday, Nov. 21, Lesnar will have to pick on someone his own size when he takes on the undefeated 6-foot-3, 262-pound top contender Shane Carwin at UFC 106: LESNAR vs. CARWIN, live from the Mandalay Bay Events Center in Las Vegas, Nev. Also on the card, one of the brightest stars in UFC history returns, as former light heavyweight champion Tito Ortiz battles UFC Hall of Famer Mark Coleman in what promises to be a ground war of epic proportions.

"Brock Lesnar has been tearing through everyone over the last year," said UFC President Dana White. "But in Shane Carwin, he's not only fighting someone as big as he is, he's fighting someone who has ended all of his fights in less than three minutes. This is literally the biggest heavyweight title fight ever and may also be the most explosive."

A fighter that has dominated the competition in his last three bouts, Brock Lesnar (fighting out of Minneapolis-St. Paul, Minn.) is a four-time All-American, two-time Big Ten Champion, and 2000 NCAA Division I National Champion college wrestler who has parlayed his amateur successes into a UFC world championship. A gifted athlete with the size, speed and power to impose his will on any opponent, the 6-foot-3 ½, 265-pound champion with a 4-1 professional record earned the UFC heavyweight title with a second-round TKO victory over UFC Hall of Famer Couture, then successfully defended his title at UFC 100 in impressive fashion with another second-round TKO against former UFC champ Mir. Now the 32-year-old Webster, South Dakota native looks to put the first blemish on Carwin's record.

"I'm excited to get back in the Octagon on November 21st to defend my title," Lesnar said. "I'm looking forward to fighting Shane Carwin. "He's undefeated and I'm the man who is going to put an end to that."

Shane Carwin (fighting out of Denver, Colo.) has done nothing short of destroying his competition. The former NCAA Division II national wrestling champion and All-American college football player has put away all three of his UFC opponents in under two minutes. The 34-year-old from Greeley, Colo. handed TKO losses to Christian Wellisch and Neil Wain before turning heads in the mixed martial arts community with a devastating 69-second knockout victory...
