Game of Thrones' 'The Mountain' faces off against UFC champion, Conor McGregor

Dream bouts are often conversations saved for late night drinking sessions but this one has actually come true.

Well, a three-minute sparring session; but it’s with UFC’s poster-boy and Featherweight Champion, Colin McGregor and the most feared character in the Game of Thrones series, ‘The Mountain’.

Hafthor Bjornsson, who plays ‘The Mountain’ character, ought to have an advantage as he towers over McGregor by one foot and weighs nearly three times the UFC fighter.

But McGregor holds his ground and even manages to force Bjornsson to the floor.

This is not the first time Bjornsson has been humbled by athletes smaller than him.

In September, he lost to two-time arm wrestling champion Devon Larratt in an arm wrestling contest.
