The UFC on FOX 9 card set to take place in Sacramento on Dec. 14 continues to take shake, as the UFC announced Sunday that Pat Healy and Jamie Varner will square off in a lightweight battle.

Varner has gone 2-2 since coming to the UFC in 2012, including a surprising upset victory over Edson Barboza at UFC 146 in a replacement role. Since then he has traded wins and losses, with his last two fights -- against Melvin Guillard and Glieson Tibau -- having gon to split decisions. He was on the wrong end of the scorecards in his outing against Tibau at UFC 164 in Milwaukee.

As for Healy, he has had a checkered run in the UFC since the Strikeforce buyout. He had a dominant victory over Jim Miller, in which he was awarded submission and fight of the night honors, converted into a "no contest" after he tested positive for marijuana at UFC 159. In his follow-up fight against upstart Dagestani fighter Khabib Nurmagomedov, Healy lost a one-sided unanimous decision.
