"When I heard the stuff he was saying, I was like, "That's concussion talk", McGregor said.
Since his departure, Malignaggi has been critical - that's putting it mildly - of the way he's been portrayed by McGregor on social media. The spars were not good for him.
Malignaggi would go on to say that McGregor got the better of him over the first five rounds, but said he took over from the sixth round and beyond.
"He was flattened against the ropes; multiple times the ropes kept him on his feet".
"I stopped doubting Conor McGregor a long time ago".
Thoughts on the footage of McGregor and Malignaggi? We were anxious about him.
Nicola Fitton, Managing Director at Betsafe, said: "We are delighted to announce our new partnership with Conor McGregor".
The other video posted by White, shows McGregor clearly landing a series of punches against Malignaggi, including a head-rocking left. "There's going to be a lot of stars at these events, especially in the high-priced ticket range, the ringside seats", StubHub spokesman Cameron Papp said.
Mayweather is the heavy favourite having gone 49 bouts undefeated with McGregor never stepping into a professional ring.
Smith made the same mistake in the lead-up to Horn's win over Pacquiao, calling him Joe again, before unloading on the judges.

"Let him speak (to Mayweather)".
"I'm preparing to win, and to win in devastating fashion".
"But no matter what a man says, if they show up and try to answer that and try their best, you've gotta give respect".
