A former interim champion and a fighter on a six-bout win streak have been added to UFC on FOX: Pettis vs. Thomson, as Carlos Condit squares off with Matt Brown.

The two will meet December 14 from Sacramento. Already, the card features UFC lightweight champion Anthony Pettis vs. Josh Thomson and Urijah Faber vs. Michael McDonald.

Condit (29-7) snapped his two-fight losing skid by avenging a previous loss to Martin Kampmann in August. Brown, meanwhile, has won six straight to improve to 18-11 overall and 11-5 with the promotion.
