McGregor's whiskey an official sponsor of UFC 229

Plenty of negotiations go into any affair that includes Conor McGregor.

The worldwide UFC star is making his return to the Octagon on Oct. 6, and it's possible the promotion had to make some concessions to assure McGregor's presence.

McGregor recently launched his own Irish whiskey and, according to the fighter, the logo will feature prominently on the mat at UFC 229.
