UFC 193 is over and will go down as the day that the legendary female MMA champion Ronda Rousey was defeated by Holly Holm, ending her undefeated career streak. UFC 194 will follow and as showcased in a recently released promo trailer, it is set to be just as iconic, with two championship matches on the line.

The highlight of the upcoming match is that between UFC Featherweight Division Champion Jose Aldo and UFC Featherweight Interim Champion Conor McGregor.

As pointed out in a report from MMA Mania, the two have been taunting each other for the better part of the year and were set to fight at UFC 189 until their match was postponed due to Aldo suffering a rib injury. Following his recovery, Aldo and McGregor will be facing off against each other for the featherweight title unification match.

While Aldo and McGregor's fight will be the main event, the main card for the night also reveals that UFC Middleweight Champion Chris Weidman will be fighting to defend his title and the belt against the current number one contender, Luke Rockhold.

The main card, as posted by Bleacher Report, will also include a match between Yoel Romero and Ronaldo Souza as they step up for a title eliminator match. The remaining fights for the main card include a match between Demian Maia and Gunnar Nelson as well as a fight between Max Holloway and Jeremy Stephens.
