Conor McGregor took a lot of people by surprise yesterday when he announced his retirement from UFC and MMA fighting in general -- although, for what it's worth, he announced a retirement back in 2016, too.
Part of me thinks he may be WWE-bound, just because of Twitter smack talk he's sent to wrestlers before, and this little nugget from former fighter-turned-WWE superstar, Ronda Rousey.
It's that wink..
