D'Arcy required treatment after being picked up by Nonu and dropped to the ground head first.

Nonu was cited after the game by International Rugby Board commissioner Douglas Hunter and will appear before appointed judicial officer Judge Wyn Williams QC at a London hotel.

New Zealand won the game 45-7 with a scintillating display of attacking rugby - but it was Nonu's challenge on D'Arcy which dominated many of the headlines on Sunday morning.

The incident brought back memories of the infamous spear tackle which left British & Irish Lions captain Brian O'Driscoll with a dislocated shoulder and unavailable for Ireland's autumn internationals.
