Promotion doesnt even start till final two weeks and really the majority of promotion is done during fight week.
If he doesnt show up to do a press conference or interviews during fight week then its an issue.
But I doubt UFC even wanted a world tour, for what? Spending money flying them around to do something you can do in one press conference during fight week. Not to mention more times they are face to face the greater chance of something bad between them or their camps happening.
Really just need to show up for one press conference, the weigh ins, have a good face off that builds interest without getting too crazy and the fight sells through the roof.
Shits a month away, 228 hasnt even happened. Just wait until you start seeing ESPN talking about it, Dana doing interviews and Conor/Khabib coming face to face. Fight week will blow up.
Just look at GGG/Canelo 2, no world tour or anything, fight is next weekend. Next week you'll see the real build up for that fight and it will sell great. Same with Conor/Khabib in a month. Shit he can do what Ronda did and still sell. She didnt do shit in the Nunes fight and it still sold a million buys on a Friday card just cause it was her comeback fight.
