Sam Warburton blamed the Lions' defeat to the Highlanders on a couple of things

Sam Warburton blamed indiscipline for the British and Irish Lions' 23-22 defeat by the Highlanders in Dunedin.
The Lions slumped to the second loss of their four matches to date despite leading 22-13 in the 54th minute, paying the price for conceding 12 penalties to the hosts' five.
