At UFC 143, former Strikeforce champion Nick Diaz and former WEC champion Carlos Condit will clash to determine which fighter will claim the interim welterweight title and a future fight with injured champion Georges St-Pierre.
In addition to the bout between Diaz and Condit, Roy Nelson will welcome Fabricio Werdum back to the UFC in a bout that could put the winner back in contention for the heavyweight title.
Werdum left the organization after a knockout loss to Junior dos Santos in October 2008. Since then, the Brazilian fought four times under the Strikeforce banner, becoming the first fighter to legitimately defeat all-time great Fedor Emelianenko.
Also, in a bout that could potentially determine the next bantamweight contender, Renan Barao will fight former WEC top contender Scott Jorgensen on the UFC 143 main card.
Before Saturday's event, the fighters will hit the scales at the Mandalay Bay Events Center in Las Vegas on Friday at 7:00 p.m. ET.
