New Zealand flanker Adam Thomson has been cited for stamping on Scotland forward Alasdair Strokosch during the side's Test match at Murrayfield.
Thomson was reported by independent International Rugby Board citing commissioner, Ireland's Murray Whyte, following the 43rd-minute incident.
A statement issued by Six Nations organisers, who oversee autumn Test disciplinary matters, said Thomson would face a disciplinary hearing in London tomorrow.
Thomson was sent to the sin-bin by referee Jerome Garces on advice from touch judge Simon McDowell. TV replays showed that Thomson brought his boot down on Strokosch's head, suggesting he was fortunate to escape with only a yellow card.
New Zealand cruised to a 51-22 victory, but Thomson now faces a ban that could rule him out of the world champions' remaining autumn Tests against Italy next Saturday, followed by Wales and then England.
Australia lock Rob Simmons, meanwhile, will also appear before an independent IRB judicial officer tomorrow.
Simmons was cited for a dangerous 'tip' tackle on France flanker Yannick Nyanga midway through the second half of Australia's 33-6 defeat against Les Bleus in Paris.
Elsewhere, prop Tendai Mtawarira has returned home from South Africa's tour of Europe following his withdrawal from Saturday's Test against Ireland due to heart palpitations.
Springbok coach Heyneke Meyer said: "We've consulted with ' Beast' and his cardiologist in Durban and although it's safe for him to play, we decided it would be best for him to return home and rest."
