McGregor posts video of boxing training

"The Notorious" Conor McGregor shared a brief clip of himself practicing the sweet science on Instagram on Wednesday, the first glimpse of him throwing hands since he took the UFC lightweight title from Eddie Alvarez last November.

There's no jiu-jitsu or kicking to see here, which makes sense, as McGregor has vowed that the next time you see him fight, it will be in a boxing match with megastar Floyd Mayweather, not the Octagon.
