Floyd Mayweather has claimed he was paid £2million to post a video in which he claimed he was negotiating a rematch with Manny Pacquiao.
The footage, which circulated on Sunday night, was several months old and was filmed during Mayweather's trip to Saudi Arabia.
In it Mayweather said he was due to hold talks over fighting Pacquiao for a second time following their richest fight in history in 2015.
But he later clarified that he had no intention of fighting his rival again, and has since doubled down.
Posting on Instagram, he said: "There is a video circulating that I made eight months ago about a Mayweather-Pacquiao rematch.
"I got paid $2,200,000 to make the video. The truth is, the fight will never happen again.
"Now, swipe left and look at the money that got wired to me for the video. Now, who’s the smart one ? I’m making millions just for 10 second video drops."
Mayweather also posted pictures of two money transfers, one for $1.2m and another for $1m.
On Monday, he told Fight Hype: "The video that y'all been seeing is false because I've been and went to Saudi Arabia. I went there a long time ago.
"I talked to them about me fighting there, just different fights, but they wanted me to specifically say Manny Pacquiao.
"And actually, we didn't just talk about boxing; we talked about different events; us bringing different events out there.
"Basically, that's an old video. At the end of the day, there's no talks about me and Manny Pacquiao fighting a rematch.
"Even if we did fight, all they're going to do is have an excuse, just like the first time.
"But as far as me and Manny Pacquiao, as of right now, it will never be a rematch."
