The UFC's year-end card in Las Vegas continues to shape itself up with the addition of a lightweight fight to the card.

Michael Johnson (13-8 MMA, 5-4 UFC) will meet Gleison Tibau (28-9 MMA, 13-7 UFC) at UFC 168 in December. UFC officials announced the new fight booking Wednesday night.

Featuring two heavily anticipated title fights with middleweight champ Chris Weidman vs. Anderson Silva and women's bantamweight champ Ronda Rousey vs. Miesha Tate, UFC 168 takes place Dec. 18 at Las Vegas' MGM Grand Garden Arena.

The main card airs on pay-per-view following prelims on FOX Sports 1 and Facebook. Johnson vs. Tibau is likely to be part of the preliminary card.
