Randy Couture

After losing two out of three fights to Ultimate Fighting Championship light-heavyweight champion Chuck Liddell and a tearful retirement in 2006, it was believed that Randy Couture had run out of chances. But before a packed house at the Nationwide Arena on Saturday, the 43-year-old UFC Hall of Famer pulled another surprise, dominating Tim Sylvia for five rounds, scoring a shutout decision that earned Couture a third UFC heavyweight championship.
