The world's largest fight promotion returns to pay-per-view this coming Dec. 10, 2011, at the Air Canada Centre in Toronto, Ontario, Canada, for UFC 140: "Jones vs. Machida."

The event features Light Heavyweight Champion Jon Jones defending his title for the second time against a man many feel has all the tools to dethrone him, former belt holder and Karate master Lyoto Machida.

That's not the only great fight on the card, though, as former heavyweight champions and bitter rivals Frank Mir and Antonio Rodrigo Nogueira will hook 'em up for a second time to prove who really is the better of the two.

And don't forget about the return of "The Huntington Beach Bad Boy," Tito Ortiz, who will take on Antonio Rogerio Nogueira in a light heavyweight match-up.

Looks like a great night of fights, no? For all the latest UFC 140 news and notes click here.
