UFC 143 goes down tomorrow night on pay-per-view, and the interim welterweight title will be on the line in the main event between former WEC champion Carlos Condit and former Strikeforce champion Nick Diaz.
Diaz returned to the UFC last October when he defeated B.J. Penn by unanimous decision. Condit is currently riding a four-fight winning streak, with wins over Dong Hyun Kim, Dan Hardy, Jake Ellenberger and Rory MacDonald.
The winner is anticipated to fight undisputed champion Georges St-Pierre later this year if the pound-for-pound star is ready to ready. He was forced to pull out of a scheduled fight with Nick Diaz after suffering a knee injury in training late last year.
In the co-main event, Fabricio Werdum returns to the Octagon to face former Ultimate Fighter winner Roy Nelson.
Also on the card is a bout between welterweight standouts Josh Koscheck and Mike Pierce. Both will be looking to face the winner of the main event or a top contender in the division. This is their chance to take a big leap in the division, especially for Pierce.
