According to Mayweather, yes. Yes, he did.

What's being called "The Money Fight," and "The Fight Of The Century" has definitely had it's face in the media. So much so that UFC's Conor McGregor and boxing's Floyd Mayweather even went on a press tour that went to four cities across 3 different countries.

You may have heard the controversy of McGregor's former sparring partner Paulie Malignaggi, who is a former IBF junior welterweight champion. After pictures came out that looked like McGregor had knocked him down, Malignaggi left the camp, and went on a tirade that he wasn't knocked down from a punch, but a push. He has repeatedly called for the full video of the sparring session to be released. UFC president Dana White has released at least two videos of them sparring, which made it look like it was extremely possible that McGregor did indeed knock him down with a punch, and not a push.

Now, the day before the fight, it seems that McGregor may have gotten played by Mayweather, who claims to have sent Malignaggi to McGregor's camp to spy for him.

Or, it could just be Mayweather's last play to get into McGregor's head. You decide.
