Nurmagomedov made McGregor tap out during Saturday's UFC 229 main event, but instead of celebrating his accomplishment, the Russian fighter sparked a big post-fight melee when he leapt over the cage and jumped into the crowd, while members from his corner entered the octagon and attacked McGregor.
He has already had his fight purse withheld - said to be $2 million - and UFC chief Dana White has said sanctions from the Nevada state authorities are likely.
McGregor (21-4) suffered a fourth-round submission loss to Nurmagomedov (27-0) at UFC 229 last weekend in Las Vegas.
Diaz is set to make his return against number three-ranked lightweight Dustin Poirier in the main event at UFC 230 in NY in November, and should he emerge victorious, McGregor could be next in line.
"We have to see what happens. can these guys get visas and get back in the country?"
Khabib Nurmagomedov is in huge trouble, and it has nothing to do with what the UFC lightweight champion did inside the Octagon on Saturday night.
Khabib's father and trainer, Abdulmanap Nurmagomedov, would be a dream match-up for him, which might factor in his son's thinking.

Before taking over at Interpol, Meng Hongwei was deputy minister in charge of public security in China. Here are some facts about Meng that might have a bearing on his disappearance during a trip to China.
As the fall-out continues from the violent scenes inside and outside the Octagon after Nurmagomedov had forced McGregor to tap out, we were joined by MMA Fighting's Deputy Managing Editor Marc Raimondi to discuss UFC229 and where that leaves the key protagonists.
Three individuals were arrested, but were released after McGregor declined to press charges. He said that the UFC will also hand over footage from the melee to the Atheltic Commission for further investigation into the matter.
While Khabib vs McGregor II would definitely do numbers, there are other fighters who are looking for a title shot as well.
"We knew some things could happen after this fight, so we had everything in place to make sure that didn't happen", White said.
"If you want Khabib", said Rockhold, a former UFC middleweight champion, "he'll want a record-breaking number". The episode worsened when an unidentified associate of Nurmagomedov jumped into the cage and struck McGregor with two sucker punches to the back of the head.
"It's always both. We could do one or the other, but at least in the chair's mind, I think the commission will be entertaining a recommendation from the attorney general that will include both".
"This is not my best side.my father is going to smash me when I get home", Nurmagomedov said. When you have such an fantastic event that we've worked hard to build over the last several months and it goes flawless, I mean literally it was too eerie.
