It’s no longer a case of if, but when Jon Jones will move up to the heavyweight division. The sport needs it, he needs it and the UFC needs it. It has become inevitable. The only question that remains is, how would he fare?

If ‘Bones’ can put the 205lb division back in order – by taking out former heavyweights Daniel Cormier and ‘Rumble’ Johnson – the big boys will be next. But despite his peerlessness at light heavyweight, MMA’s biggest division is a whole different game.

No prize in sports generates interest like the heavyweight championship of the world. Winning it would guarantee Jones eclipses MMA’s other all-time greats, like Anderson Silva and Georges St Pierre, and shine on his own as the greatest fighter we’ve ever seen. But can he do it? Find out what he needs to do to beat some of the weight class’ best.

Also in this heavyweight packed issue, former champion Junior dos Santos begins his campaign to reclaim his belt, ‘The Black Beast’ Derrick Lewis plans his next knockout and no-holds-barred pioneer Don Frye picks out his most memorable moments in the ring and the cage.

We also catch up with Ronda Rousey, Michael Chiesa, Daniel Straus, Amanda Nunes and a whole host of other stars destined for the UFC 200 triple-header – including a private gym session with Rafael dos Anjos. And we pop a bottle with Bruce Bu er to toast his 20- year anniversary announcing in the Octagon.

Pound-for-pound debate – Is Demetrious Johnson the real world number one?

With so much Jon Jones in this issue we thought it only fair to shine a light on his biggest rival for the elusive pound-for-pound number-one spot. Flyweight king Demetrious Johnson’s reign as the UFC’s first and only 125lb champion has been utterly dominant, and he tells FO why he ranks himself as the greatest mixed martial artist fighting today. He also discusses his ambitions and what it would take to make him put down his dishes and prepare for super-fights in the bantamweight division.
