Rafael dos Anjos better be careful. Conor McGregor is back in the gym, literally training his ass off. One of the most gifted athletes in MMA and easily one of the sport's hardest workers, watching McGregor train is like watching a race horse gearing up for the Preakness.
Take a look and see for yourself:
UFC 197 features Rafael dos Anjos and Conor McGregor fighting for the lightweight championship. If McGregor wins, he'll be the first UFC fighter to ever hold the featherweight title and the lightweight title at the same time.
