For a man who signed a non-disclosure agreement, Paulie Malignaggi sure isn’t afraid of speaking out about his brief time as Conor McGregor’s sparring partner.

Just over a week after first slating McGregor on Ariel Helwani’s MMA Hour, former IBF and WBA champ Paulie Malignaggi was at it again.

Malignaggi, who quit the McGregor camp as a sparring partner after leaked photos of the two appeared on social media, made disparaging comments about McGregor's remaining sparring partners.

His words come just days after UFC president Dana White leaked two videos of the same sparring session ahead of McGregor’s August 26 fight against Floyd Mayweather Junior.

The videos appear to show McGregor flooring the Brooklyn native and landing a hard left from long distance on Malignaggi’s chin.

Speaking on Monday’s MMA Hour, Malignaggi referred to UFC fighter Artem Lobov, a long-time McGregor sparring partner, as “like a punching bag.”

He went on to say: "He's using a no-name amateur and a couple of MMA guys.

"One of them, Artem, I thought was like a punching bag. I thought you might as well use a punching bag instead of hitting him. I didn't think there was enough quality for him, especially now that I left."

Malignaggi’s comments fit into a larger narrative the current Showtime pundit’s been pushing for about a week.

Malignaggi contends that the McGregor camp are supplying Notorious with softer sparring partners than necessary, in an effort to boost the UFC champion’s confidence.

As Malignaggi said: “You’re getting ready for the best fighter that ever put on boxing gloves…You’re supposed to be willing to suffer in camp.”

Though, Malignaggi touted the abilities of McGregor's sparring partner Dashon Johnson. He said that Johnson had hardly been used, with the McGregor camp preferring to use “a no-name amateur (Tyrone boxer Tiernan Bradley) and some MMA guys.”

Malignaggi believes he was brought on to make McGregor look good, a tactic which backfired for the Irishman, as accomplished boxers Andre Berto and Steve Hook turned down invitations to spar in the wake of the photo leak.

Malignaggi went on to imply McGregor is deluded to think he will beat Mayweather, referring to McGregor as “adorable” and “The Little Engine That Could.”

So, what’s the real story here?

Well, it appears Malignaggi’s pride was hurt by his perceived ill-treatment by the McGregor camp, who, he says, put him up in a “crack house” and insisted on having him spar for a full 12 rounds instead of the usual four to six.

This was then compounded by the photo leak, which prompted Malignaggi to very publicly leave the McGregor camp on August 4.
