Wallabies celebrations for clinching the Tri-Nations rugby crown have been tempered by news playmaker Quade Cooper is in danger of missing World Cup matches after being cited for kneeing All Blacks skipper Richie McCaw.
Cooper will face a SANZAR judicial hearing in Brisbane today (4pm NZT) for his part in a second-half incident in Australia's 25-20 victory at Suncorp Stadium.
The volatile first five-eighth has been cited for allegedly striking McCaw in the face as he attempted to leave a breakdown.
There is little love lost between the pair on the field -- they have clashed several times in the past 10 months and it wasn't the only occasion tempers flared in their personal battle last night.
A suspension would rule Cooper out of the Wallabies' opening World Cup matches, with the tournament kicking off on September 9 in New Zealand.
