UFC 140: "Jones vs. Machida" is set to take place at the Air Canada Centre in Toronto, Ontario, Canada on Sat., Dec. 10, 2011, in the promotion's return to pay-per-view (PPV).

Headlining the event is an intriguing light heavyweight championship bout pitting titleholder Jon Jones against former champion Lyoto Machida. It should be a barnburner.

But that's not all.

Also penciled in for the UFC 140 fight card is a heavyweight rematch that should see a definitive conclusion to the rivalry between Frank Mir and Antonio Rodrigo Nogueira. And don't forget about the freshly christened "People's Champ," Tito Ortiz, who will square off against Antonio Rogerio Nogueira.
