McGregor deletes insult aimed at Russian star

UFC star McGregor has again hit out at Russian fighter online

Conor McGregor hasn't been seen in the cage for more than a year but that hasn't stopped him from taking aim at his UFC rivals after he tweeted (and subsequently deleted) a vile insult at Russian title challenger Islam Makhachev.

McGregor is known for being one of the more silver-tongued fighters in combat sports history but has been known to get himself into an array of trouble for some of his more egregious statements, and despite coming up second-best in his heated rivalry with Khabib Nurmagomedov, McGregor has taken to lobbing verbal bombs at the man considered to be Khabib's successor. 

In the since deleted tweet, McGregor appeared to suggest that Makhachev's parents were cousins - but later thought better of it and removed it from his official Twitter page. 

McGregor has been a frequent purveyor of the tweet-and-delete strategy online, though it remains unknown if he is persuaded to remove the offensive messaging by members of his team or if he simply decides to himself. 

For all his outspokenness, McGregor remains linked to several large brands and was recently confirmed as having a starring role in the upcoming 'Road House' reboot of the popular 1980's action movie. 

Conor is gearing up to make a super fight against Islam if he wins in October
