Australia centre Tevita Kuridrani will miss the remaining November Internationals after being suspended for five weeks.
Kuridrani was shown a straight red card in Australia's 32-15 win over Ireland last Saturday for a tip tackle on Peter O'Mahony.
Kuridrani appeared before International Rugby Board (IRB) judicial officer Professor Lorne Crerar on Tuesday, with Crerar judging the offence to be mid-range after hearing representations from the player and viewing footage of the incident.
Upholding the red card given to Kuridrani and placing the starting point for a suspension at eight weeks, Crerar added an extra week as a deterrent to others against a similar offence, but cut off four weeks in mitigation due to Kuridrani's good disciplinary record and other factors.
Working around Kuridrani's playing schedule, the Brumbies back is suspended until February 16, 2014.
The suspension means that the Wallabies will be without at least six players against Scotland on Saturday, with Nick Cummins, Adam Ashley-Cooper, Liam Gill, Benn Robinson and Tatafu Polota-Nau all suspended after a late-night drinking session in Dublin last week.
