Conor McGregor has accused Islam Makhachev's parents of being "cousins" in his latest jibe at his UFC rival.
McGregor has not fought in the octagon since last July when he broke his leg in a defeat to Dustin Poirier, but has engaged with many rivalries on social media. In his crusades online, McGregor has launched scathing insults against a number of his enemies including Khabib Nurmagomedov and his protege Makhachev.
Late last year, McGregor branded former opponent Nurmagomedov a "smelly inbred" when launching a later deleted allegation that the culture of his hometown Dagestan involves 'inbreeding'. He also aimed the brash attack on Makhachev who is from the same part of Russia, after the rising star hit out at McGregor.
