The war of words continues. Former two division champion Paulie Malignaggi has continued to lash out at UFC superstar Conor McGregor.

This past Saturday night, the MMA fighter was stopped in ten rounds by five division world champion Floyd Mayweather Jr.

McGregor, a two division champion in the UFC, was making his professional boxing debut. Malignaggi, as part of the Showtime broadcast team, was sitting ringside at the T-Mobile Arena in Las Vegas.

Malignaggi, who retired from boxing earlier this year, was hired as a sparring partner by McGregor, to help the UFC fighter prepare for the scheduled battle with Mayweather.

The two of them had a bad falling out. Malignaggi became enraged after members of McGregor's team released images of their second sparring session on social media.

The images painted what Malignaggi claimed was a "dishonest" picture of the sparring session - as one image showed Malignaggi down on the mat from a claimed knockdown and other images showed him taking punishment.

Once the images came out, Malignaggi immediately quit McGregor's camp.

Then UFC President Dana White released hand-picked video clips from the sparring session. One clip showed a debatable knockdown of Malignaggi and the other had McGregor doing damage.

McGregor has claimed in several interviews that Malignaggi took a beating that was so severe, that everyone was worried about him because he was stumbling around even hours after the sparring session.

The two of them had a heated face to face confrontation last Tuesday at T-Mobile, while McGregor was making his grand arrival for the fans and media.

McGregor started very strong against Mayweather, but he fatigued badly as the fight played out and was eventually stopped in the tenth round.

Malignaggi believes McGregor "quit." He feels McGregor intentionally stopped fighting, because he wanted referee Robert Byrd to jump in and wave off the contest.

“If you get tired you don’t quit, I’m sorry. In MMA you can put yourself in a position to be submitted, not fight off the submission then you can tap out. There’s a way to cop out in MMA, there’s no way to cop out in boxing," Malignaggi told MMA Fighting.

“You did not throw a punch for a minute straight while you were being assaulted. The bottom line is he didn’t want to go out on his back, he wanted Byrd to save him. Because if you don’t want Byrd to save you, you’ll show some signs of life, you’ll throw a punch. You’ll say, ‘Yeah I’m hurting but I want to remain in this fight, I don’t want to be pulled out of this fight. He did none of that, he threw no punches, he was waiting for Byrd to stop the fight. He can say anything he wants, but he can’t edit this video.”

Malignaggi then double-downed on his vow to return to the sport for a boxing match with McGregor - to settle their differences in the ring.

"The guy has no balls. When you back him into a corner he’s a little pussycat. He quit. If you don’t throw a punch for over a minute, you quit buddy. You can explain it any way you want ... you quit buddy, you absolutely did. I don’t like the guy, I never will like the guy, personally I think he’s a scumbag. Just the fact I could sink my fist into his face — I would love that. The fact I could get him looking like the sissy that he is — I would love that," Malignaggi told reporter Luke Thomas.
