UFC 194 now will feature two title fights as middleweight champion Chris Weidman faces Luke Rockhold in the new co-main event on Dec. 12 in Las Vegas.

The fight, announced on "SportsCenter" on Thursday night, joins the featherweight title unification bout between Jose Aldo and Conor McGregor which will headline the card at the MGM Grand Garden Arena..

Weidman and Rockhold have been on a collision course for several months, just waiting for the UFC to pick a date and location.

Weidman will make the fourth defense of his UFC middleweight title since winning the belt from Anderson Silva in 2013. Most recently, Weidman dispatched Vitor Belfort by TKO in the first round at UFC 187.

As for Rockhold, he’ll earn his first crack at UFC gold since joining the promotion as the last Strikeforce middleweight champion.

Rockhold has suffered only one bump in the road since joining the UFC, losing to Belfort in his debut, and he’s since reeled off four wins in a row, including a submission victory over former champion Lyoto Machida in his last fight.

More fights are expected to be added to UFC 194: Aldo vs. McGregor in the coming days.
