Previous Lions captains Paul O'Connell ( from 2009 ) and Brian O'Driscoll ( 2005 ) were also chosen . Dylan Hartley was initially selected but was removed from the squad before the squad departed , after being suspended for 11 weeks for abusing a referee . [ 12 ] Rory Best replaced Hartley later that day , [ 13 ] meaning that the squad that set off to Hong Kong on 27 May consisted of 15 Welsh , 10 Irish , nine English and three Scottish players .

[ 21 ] Ireland prop Tom Court was called up on 23 June before the final mid-week fixture against Melbourne Rebels , allowing Mako Vunipola to miss that match . Alex Corbisiero had injured his calf in the first test , so the Lions faced a shortage of props . Court was already in Australia visiting his home town of Brisbane .

Wales head coach Warren Gatland was the Lions' head coach, and their tour captain was Sam Warburton.
