THE MAIN EVENT

Jon Jones is, quite simply, the best fighter in the UFC today. He's a two-time UFC light-heavyweight champion who never lost his belt in the cage and is now on a path to redemption after a troubled career that has seen him caught up in a plethora of issues, both in the sport and away from it.

But now he's back on form, clean of his anti-doping issues and ready to reassert his dominance on the UFC's light-heavyweight division.

But Anthony 'Lionheart' Smith has other plans.

The straight-talking former middleweight campaigner has seen his career hit its highest point since his move up to light-heavyweight. Fighting at his more natural weight, Smith looks every inch a legitimate world title contender, but the bookies have already counted him out.

Jones has been rated a 1/12 shot to beat Smith tonight, but Smith says he feels "like a criminal, because I know something nobody else does". His approach to fight week has drawn praise even from Jones, who was suitably impressed with Smith's interviews and confident demeanor ahead of the fight.

But talking a good game is one thing. Translating it to the cage in a world title fight is quite another. And doing it against possibly the best pound-for-pound fighter on the planet makes it a mountainous task.

Can Smith overcome the odds - and Jones - and capture the title, or will Jones extend his unbeaten streak in world title fights to 13?

It's going to be a fascinating matchup.
