The UFC returns to Las Vegas this Saturday for UFC 143.

Taking place at the Mandalay Bay Events Center, the event will be headlined by an interim-welterweight championship bout between former-Strikeforce champion Nick Diaz and former-WEC champ Carlos Condit.

The bout came to surface following an injury to champion Georges St-Pierre.  He was expected to meet Diaz at the event.  Condit was originally expected to take on Josh Koscheck but was promoted to the main event following the injury; Koscheck will now meet Mike Pierce.

The main card will air live on pay-per-view with preliminary contests airing on FX and Facebook.
