Two more fights have been placed on the year-end UFC 168 card from Las Vegas, officials announced recently.

Diego Brandao meets Dustin Poirier at featherweight, while Chris Leben takes on Uriah Hall in a middleweight scrap.

Placement of both bouts is currently unknown for the December 28 card that features two championship matches. Chris Weidman puts the middleweight belt on the line vs. Anderson Silva, and Ronda Rousey faces Miesha Tate for female bantamweight gold.

Brandao (18-8) has won three straight and is 4-1 with the promotion, including becoming the winner of The Ultimate Fighter 14. Poirier (14-3) is coming off a key win over Erik Koch and is now 6-2 inside the Octagon.

Leben (22-10) and Hall (7-4) could be fighting for their respective UFC careers. Leben has lost three straight and four of five, while Hall is 0-2 with the promotion.
