Light heavyweight title-contender Alexander Gustafsson has spent years studying inside an eight-sided classroom for the test he’s scheduled to take on Saturday night when he faces champion Jon Jones at UFC 165. The 26-year old Swede has racked up a 15-1 record in his career including success in six straight showdowns and should be fully prepared to try and deliver the first legitimate loss of Jones’ career. Aiding “The Mauler” in his quest to wear divisional gold will no doubt be the experience he has compiled in the cage against a number of tough opponents including a former UFC champion.
