The Irishman will take on the long-reigning featherweight champion in a title unification bout in the main event, which has been hyped as the most anticipated PPV of the year.
McGregor was originally supposed to collide with Aldo at UFC 189, but the Brazilian suffered a rib injury and was forced to pull out at the last minute. "The Notorious" took on late replacement Chad Mendes in the new main event and TKO'd the American in the 2nd round to claim the interim 145 lbs. title.
McGregor posted a video on Instagram yesterday to showcase his lean physique heading into the bout - check it out below.
"That's light work," according to the 27-year-old.
The UFC 194 extravaganza will take place at the MGM Grand Garden Arena in Las Vegas, Nevada on December 12th.
