Conor McGregor shocked UFC fans over the weekend when he announced that he would be retiring from the sport. McGregor has retired three times over the last four years and every single time, he ends up coming right back to the Octagon. With this in mind, many are skeptical of McGregor's announcement although at least for now, they are taking it seriously.

McGregor had been teasing numerous fights and now it looks like they are all being abandoned. One of the fights people were excited about was a boxing rematch with the likes of Floyd Mayweather. As you can imagine, Mayweather was quick to find out about McGregor's retirement and immediately took to Conor's IG page to take some shots. Floyd pointed out that McGregor was talking a big game and now, he is simply throwing it all away.

Per Mayweather:

"If I’m not mistaken, didn’t you tell Mike Tyson you could beat me if we fought a second time? Now you’re quitting! I thought you wanted to beat the best? Well, if you decide to come back, I will be waiting to punish you again."

Based on this comment, it seems as though Mayweather is truly upset about having to miss out on a rematch with McGregor. However, if McGregor decides to come back, now we know a rematch is certainly in the cards. Not to mention, the trash-talking will lead to some great promotion.
