Australia captain James Horwill is in danger of missing the rest of the series against the British and Irish Lions after being cited for stamping.
Horwill is accused of stamping on the head of second row Alun-Wyn Jones in the third minute of the Lions 23-21 win at Suncorp Stadium and faces a disciplinary hearing in Melbourne at 10.30am BST.
Lions coach Warren Gatland confirmed the tourists had referred the incident to the match citing commissioner after the match officials failed to spot the incident.
"Alun's fine. The medical team had a look at him at half time and at full time they had to put a couple of stitches in his eye," he said.
"We had a look at him after the game and the feeling from us was that he needed to be referred to the citing commissioner to have a look and make up his mind.
"I played in the days when rucking was allowed and I've still got some scars that bear witness to the ruckings I had, but for me the head was sacrosanct and you stayed away from that.
"It's up to the citing commissioner to make any further decision."
If found guilty, Horwill could face a suspension of up to 12 weeks which would rule him out of the remaining two Tests of the Lions tour.
