The retired boxer quit as McGregor's sparring partner on Friday (AEST) after photos of their sessions were leaked on social media, with the Irishmen preparing for his much-publicised fight with Floyd Mayweather Jr.
And in a string of tweets, Malignaggi hit out at UFC star McGregor's ability in the ring ahead of the super-fight.
"This coming week I'll actually start to discuss a bit what happened (in camp), he whimpers like a girl when he gets ripped to the body," Malignaggi wrote.
"I won't speak tactics of his, that I wouldn't do, I still have some ethics I'm not Conor but def[initely] will give the story straight about stuff."
