Add another bout to the year-end UFC 168 event, as Manny Gamburyan and Dennis Siver will collide.

Officials announced the fight recently for the December 28 card from Las Vegas. It will likely be part of the prelims on either FOX Sports 1 or Facebook.

Siver (21-9) is coming off a knockout loss at the hands of Cub Swanson, while Gamburyan (13-7) topped Cole Miller in his most recent bout.

The card features two UFC championship matches, as Chris Weidman defends his middleweight crown vs. Anderson Silva and Ronda Rousey meets Miesha Tate for the female bantamweight belt.
