Video: Watch Conor McGregor take on the 'The Mountain' from Games of Thrones
Interim UFC featherweight champion Conor McGregor has taken on Hafþór Júlíus Björnsson aka Gregor 'The Mountain that rides' Clegane' from Game of Thrones in a physical sparring contest.
The Icelandic strongman is 6ft9" tall and weighs 180kg compared to the Crumlin native's fighting weight of 65kg.
It's clearly a no-holds-barred contest between the pair and McGregor wisely opted to stay at distance, hitting the big man with jabs to the mid-rift.
McGregor is deep in preparation for his bout with Jose Aldo for a title unification bout in Las Vegas on December 12.
Conor is clearly not concerned about picking up injuries before he picks on someone his own size in two months time.
