All Blacks coach Ian Foster has warned of the potential "double whammy" of a long World Cup ban for players found guilty of making high tackles, a penalty which comes on top of a possible card and which may be just as damaging to a team's hopes of progressing in Japan.
The big initial talking point at this tournament has been the initial inconsistency of the officials ruling on illegal high shots, for which they were criticised by their own organisation, and then the regular offending by players from various nations.
Four players – Australia's Reece Hodge, Manu Samoa's Rey Lee-Lo and Motu Matu'u and the United States' John Quill – have been found guilty of high tackles and all have been banned for three weeks. The entry point for sanctions is six weeks, with mitigating circumstances and good behavior all potential discount factors.
Only Quill, who hit England's Owen Farrell high with a shoulder, was shown a red card at the time.
Another, England's Piers Francis, has been cited for a hit in the opening seconds of England's 45-7 win over the USA in Kobe for which he wasn't penalised at the time.
