Once McGregor was no longer the featherweight champion, he began taking routine shots at both Jose Aldo and eventually Max Holloway, who held the title after he left the division. Everything happened so fast.
It's the fourth time a fight between the pair had to be called off.
Because McGregor has not exactly gone by the book in terms of the most recent matches he's taken, there's no guarantee that he will be interested in facing either Nurmagomedov or Holloway for the Lightweight championship that will soon be taken from him. Ferguson was scheduled to fight Nurmagomedov at UFC 223 but sustained a freak knee injury over the weekend and was replaced by Holloway on Sunday evening.
When asked about his professional relationship with McGregor, he simply said "not good".
McGregor is still recognized as the UFC lightweight champion despite having not defended the title since winning it against Eddie Alvarez in 2016.
White also said this week he did not expect McGregor to attend Saturday's UFC 223 card.
Lobov is a long-time friend and training partner of McGregor's and it is likely Thursday's incident was a response to this altercation.
Conor McGregor sure knows how to make news, if you believe all press is good press, anyway. He has legions of fans in his native Russian Federation and a risky ground-and-pound game that makes him a nightmare style matchup.
The Notorious has not fought in the octagon since winning the 155-pound title in November 2016, instead fighting Floyd Mayweather in a losing effort inside the boxing ring.
White insisted that McGregor "is coming back this year, 100 per cent", adding, "We'll see how this thing plays out [with the lightweight title], and we'll go from there". "He will fight this year".
By far the biggest superstar in MMA, McGregor's future is among the most talked-about topics in the sport. They got down to the loading docks, where the fighters were getting on the buses, and they started to attack the buses.
