Conor McGregor has been very busy since losing to Khabib Nurmagomedov at UFC 229.

With rumours of retirement spreading, the Notorious is currently touring America promoting his new whiskey brand, Proper No.12.

It's one of many business ventures McGregor has outside of UFC and according to his coach, John Kavanagh, they've barely spoken over the past week.

Kavanagh was speaking to Ariel Helwani on the American MMA show Ariel & The Bad Guy, where he explained what's been happening post-fight.

"This may actually surprise you, but I haven't spoken to Conor since the fight," said Kavanagh. "We had a couple of texts back and forward.

"After the fight he went home. I went home as well. We were in separate houses. So I was there with Artem [Lobov], Pete [Queally] and Orlagh [Hunter].

"We just stayed up Saturday night, chatting. There were a couple of texts back and forward with Conor - saying, oh I could have done this, I could have done that."

McGregor's coach was also asked about his performance and said they may have got his tactics wrong against Khabib by going too defensive.

However, there could be another reason for the defeat - even if Kavanagh doesn't want to admit it.

McGregor's new whiskey brand has taken up a lot of his time recently and Kavanagh said there was a "concern" before the fight that there was too much going on away from UFC.

"Was there any concern in the camp that there was too much going on outside of fighting? He's launching the whiskey brand..." asked Helwani.

And Kavanagh replied: "Always, that's always a concern, but that's what made him who he is. He is able to juggle things like that. It's just been part of his journey the whole way through.

"We're always vying for his attention between his other interests.

"But he is very focused. If you have a good work ethic, if you have a active mind, there is no real reason why you shouldn't.

"That's how we did it - we worked around that. That's not a reason, that's not an excuse. We got our training in and then he was doing his other bits as well. It's just part of who he is."

McGregor was far from his best against Khabib and there's a good chance his preparation wasn't as thorough if he was distracted in any way.

If the Irishman does decide to go again - and we hope he does - perhaps he would be wise to focus all his energy on UFC.
