UFC 140: "Jones vs. Machida" is all set to pop off tomorrow night (Sat., Dec. 10, 2011) from the Air Canada Centre in Toronto, Ontario, Canada.

The pay-per-view (PPV) event features a light heavyweight championship clash, as 205-pound titleholder Jon Jones puts his belt up for grabs against former ruler of the roost, Lyoto Machida.

Also on tap is a heavyweight rematch three years in the making pitting a now healthy Antonio Rodrigo Nogueira against the first man to ever knock him out, Frank Mir. Finally, Tito Ortiz will try to get back into the win column when he squares off against Antonio Rogerio Nogueira.
