Paulie Malignaggi has left Conor McGregor's camp ahead of the MMA star's fight against Floyd Mayweather Jr.
Malignaggi, who retired from the ring earlier this year, was hired by underdog McGregor to serve as a sparring partner in his training camp for the Las Vegas clash with red-hot favourite Mayweather on August 26.
The former two division world champion was angered that photos from their most recent sparring session had appeared on social media.
Malignaggi told ESPN: "I wanted to be part of this event, but I didn't want to become the story and that's what this has turned into.
The Sky Sports pundit said: "I won't release any information about his game plan or what he's working on, I wouldn't do that. But this has become a fiasco.
"It's a circus. And I do want that sparring video released. I understand it can't come out now, but Conor, if you have any balls, release what really happened.
"There was a pushdown. Conor on the inside, he can get a little rough. He shoved me down, you know, but no knockdowns."
