Australia's Darcy Swain has been suspended for six weeks for the ugly cleanout that left New Zealand's Quinn Tupaea with a season-ending knee injury.
Tupaea ruptured his medial cruciate ligament and partially tore the anterior cruciate ligament in his left knee after Swain entered a ruck and made firm contact with the All Black's outstretched leg.
Swain received a yellow card at the time but was cited after last week's Bledisloe Cup match at Melbourne's Marvel Stadium.
