Watch: Conor McGregor works on reflexes for Floyd Mayweather bout

UFC champion Conor McGregor has posted an Instagram video of himself avoiding some fast combinations ahead of a possible clash with Floyd Mayweather Jr.

The pair are set to collide later in 2017 or early 2018 in what is set to be one of the biggest Pay-Per-View events of all time.

McGregor, 27, has put his MMA career under Dana White on hold in order to sharpen his skills to face the best boxer of the last twenty years.

‘The Notorious’ had previously fought under the Queensberry Rules as a youngster back in Ireland before successfully heading into Mixed Martial Arts.
