UFC light heavyweight champion  Jon “Bones” Jones  returns to the Air Canada Centre in Toronto on Saturday, Sept. 21 to defend his title against Swedish contender  Alexander “The Mauler” Gustafsson at UFC 165. At just 25 years old, Jones is one the most dominant fighters in UFC light heavyweight history. His 12 wins are second most in the division’s history, while his five consecutive title defenses tie him with UFC Hall of Famer Tito Ortiz ’s light heavyweight record. Gustafsson, 26, enters the bout with a near spotless record, having won six straight, while holding a 15-1 all-time record (7-1 in the UFC). Injury forced him off an April card in his native Sweden, however, his previous bout saw him earn a unanimous decision over former UFC light heavyweight champion Mauricio “Shogun” Rua in December 2012. “Jon Jones is re-writing the record book for the light heavyweight division,” UFC President Dana White said.
