Two of the best light heavyweights in the world will collide this weekend.

Jon Jones will look to defend his UFC light heavyweight title for the sixth time when he faces young Swedish challenger Alex Gustaffson in the main event of UFC 165 this weekend.

The 25-year-old champion has taken his place at the top of the pile in the 205 pound division since become the youngest ever champion in the UFC back in 2011.

Since then he has decimated the competition in his division with the Rochester native now seen as the best pound-for-pound fighter in the world.

In the past, Jones has not just won fights due to his striking and wrestling skill, but also his size.

With easily the longest reach in UFC history at 84.5 inches when combined with his other physical gifts, Jones at times has the presence of a heavyweight fighter.

However, in a mouth-watering prospect this weekend Jones faces a fighter that comes as close as anybody in the past to match him in bulk and reach.

Gustaffson has won seven of his eight fights since joining the promotion, with the only bump in the road to the top of the division coming in the form of a submission loss to Phil Davis at UFC 112.

Since then he has gone on to beat some of the best fighters of the past five years in the form of Mauricio Rua, Thaigo Silva and Matt Hamill.

Gustaffson has spoken of the opportunity before him being once in a lifetime, and while this might sound good in a soundbite, even if the Swede loses this weekend, he has too much star power to fade off into the distance.

While some are tipping the champion to fall, there is not the level of buzz surrounding an upset like that were before Chris Weidman unseated Anderson Silva from the middleweight.

Jones is a once-in-a-generation fighter combining the skill, size and dedication to improving with every fight that could see him stay on top of the sport for at least the next five years.

However, as with any mixed martial arts bout, almost anybody is in with a chance and Gustaffson has everything to gain and nothing to lose.
