Conor McGregor is scheduled to make his return to UFC when he faces off against rival Khabib Nurmagomedov at UFC 229 on October 9 for the UFC Lightweight Championship.With this being McGregor's first UFC fight since he defeated Eddie Alvarez at UFC 205 in November 2016, you would think the UFC media wants to do everything they can to hype it up.However, to what might not be surprising to come, Notorious is refusing to play along despite it possibly being the biggest fight in UFC history.According to Dave Meltzer of the Wrestling Observer Newsletter, via MMA Mania, the reason why we haven't seen much media coverage of Khabib vs McGregor is because McGregor has not agreed to do any.Meltzer said: “There are no press conferences scheduled because McGregor at this point hasn’t agreed to them."There is a lot of frustration within the UFC about McGregor’s attitude, but in the end, he’s got the leverage and the ticket sales and secondary market results only give him more leverage.”Meltzer speculates as well that the reason why Notorious might not want to do any media coverage is because he doesn't want to take a break from his training for arguably the biggest and toughest fight of his career.

He said: "The feeling is that this may be the biggest non-boxing PPV of all-time, and the only reason it wouldn’t be is that McGregor hasn’t been pushing it hard.

"McGregor was able to get a larger piece of the action for this fight than any of his UFC fights to date, so there is a direct correlation more than ever between his work in promoting the fight and his pocket book, but this may also show that he knows he’s in a real fight and doesn’t want to break training."

UFC 229 is just over a month away, so you would expect promotion to the fight to begin to hot up as soon as UFC 228 is in the books next weekend.

According to MMA journalist Damon Martin, McGregor is expected to finish up his training camp in mid to late September when he arrives in Las Vegas.

This might be when we finally see Notorious speak to the media more ahead of arguably the biggest fight of his UFC career.
