Jose Aldo-Conor McGregor fight to lead rescheduled UFC 194 at MGM

A featherweight title unification bout between Jose Aldo and Conor McGregor will headline UFC 194 on Dec. 12 in Las Vegas.

UFC officials confirmed the bout to ESPN.com, following an initial report by Yahoo! Sports. The pay-per-view event is scheduled to take place at MGM Grand Garden Arena.

The UFC had been in discussions to take UFC 194 to AT&T Stadium on Dec. 5 in Arlington, Texas, but ultimately landed in Las Vegas. A previously reserved concert at MGM Grand forced the promotion to postpone the event one week.

Aldo (25-1) was originally scheduled to defend his title against McGregor at UFC 189 on July 11. Aldo suffered a rib injury while training for the fight, however, and was eventually replaced on the card by Chad Mendes.

McGregor (18-2) remained on the card and claimed the interim 145-pound title, knocking out Mendes (17-3) with punches at 4:57 of the second round. McGregor is 6-0 in the UFC with five wins by knockout.

Had UFC 194 landed in the Dallas Cowboys' 100,000-plus capacity stadium, the UFC had considered booking female bantamweight champion Ronda Rousey to the co-main event.

White told Yahoo! Sports that will no longer be the case. He went on to confirm Rousey (12-0) will fight Miesha Tate (17-5), whom she has already beaten twice, at a later date.

"That fight isn't going to be on the [Aldo-McGregor] card, for sure," White told Yahoo! Sports. "If we were going to go to Dallas Cowboys Stadium, that's another story, but the MGM really wanted the [Aldo-McGregor] fight, and they made a huge effort for it and they got it. And it works out better for us to be in Las Vegas."

In regard to a potential fight between Rousey and Invicta FC featherweight champion Cris "Cyborg" Justino, White has reiterated the UFC's stance that Justino must prove she can make the 135-pound weight limit before the fight is booked.
