A new main event for UFC 152 in Toronto, Canada, was announced today with the previous top fight – Joseph Benavidez vs Demetrious Jonson for the Flyweight title – moved to the co-main event spot.

After the cancelation of UFC 151 from Las Vegas, the reigning Light Heavyweight champion Jon Jones will be defending his title against Brazil’s Lyoto Machida, a rematch from their UFC 140 main event which also coincidentally enough took place in Toronto.

Their first fight went two rounds with Jones finishing off Machida with a standing guillotine choke for the victory.

In the past few days, Jones said he would not find Machida on pay-per-view as he’s a businessman and doesn’t think Machida has the star power to sell the show.

UFC President Dana White admitted that while the Jones vs Machida fight has not been officially signed yet, Jones won’t refuse it, and if he does, he gave the impression that there would be some serious repercussions for the champion.

UFC 152 takes place on September 22.
