McGregor's trainer jokes about move to WWE

Conor McGregor's trainer John Kavanagh has been active on social media in the hours following "The Notorious One" tweeted an impromptu retirement announcement.

While it's unknown how serious Kavanagh is about his future with or without McGregor in MMA, the Dublin-based coach is teasing a move to the world of sports entertainment.

Some, actually believe McGregor is set to make the move to the WWE world, but it's highly unlikely.

There's a list of plausible reasons for McGregor's stunning announcement, which include his attempt to bargain for more money from UFC, and that he's lost his will to fight after witnessing the bout that led to the tragic death of Joao Carvvalho last week.
