McGregor boxes heavy bag in latest 'Mac Life' video

The rumors are true: Conor McGregor is boxing. Somewhere.

Hot off the heels of some scintillating sparring footage that "The Notorious" recently shared, the latest clip from "The Mac Life" sees McGregor going toe to toe with a heavy bag in what can only be preparation for his long rumored bout with Floyd Mayweather.

The opening odds for the yet-to-be signed bout were heavily in Mayweather's favor, but after seeing McGregor show off his precision punches and cat-like movement against a defenseless bag, there have to be at least a few bettors thinking twice about taking Mayweather in this one.
