With just three weeks left of the All Blacks season, the incident could bring an early close to Retallick’s campaign, which had already been shortened due to injury.
All Blacks coach Ian Foster said he expects to find out what the judiciary ruling is in terms of a suspension on Tuesday night.
“It looked pretty innocuous from a number of angles, but we’ll do our talking in the judiciary. We want to go and present a pretty strong rugby case for it, but we’ll just have to see what unfolds.
“The fact the other player bounced straight up and came back into the game, it was almost like nothing happened. But it is a game; we’ve just got to make sure we’re good in that area.”
The All Blacks have already been forced to send captain Sam Cane (cheekbone fracture) and veteran Dane Coles (calf) home due to the injuries they sustained around the Japan test, and the team would have to put forward an extremely compelling argument for Retallick to not miss time through suspension.
A low-end sanction would potentially see Retallick be available for the team’s third and final test of the tour – against England at Twickenham on November 20 – while a mid-level sanction would be the end of his season.
Despite that, it is expected both Sam Whitelock and Scott Barrett will be available for selection alongside Tupou Vaa’i for next weekend’s test against Wales in Cardiff, with Patrick Tuipulotu being released back to the All Blacks XV for their match against Ireland A.
