UFC 153: "Silva vs. Bonnar" blew the roof off the HSBC Arena in Rio de Janeiro, Brazil, last night (Sat., Oct. 13, 2012) featuring a main event of Middleweight Champion Anderson Silva knocking out Stephan Bonnar inside the first round.

As if there was ever any doubt.

The co-headlining attraction saw Brazil's favorite son, Antonio Rodrigo Nogueira, come back home and put on one hell of a show for his fans, submitting Dave Herman in the second round with an armbar.

This just over one year after he did the same -- but with a knockout -- to Brendan Schaub in front of his fellow countrymen.

Other action on the card saw Jon Fitch decision Erick Silva but in an exciting "Fight of the Night" winning affair while Phil Davis submitted Wagner Prado and Demian Maia continued his rise through the welterweight division with a tapout win over Rick Story.
