South Africa lock Lood de Jager has been cited for alleged foul play during their Rugby Championship loss to New Zealand in Durban.
De Jager made an illegal, no-arms charge into a ruck with eight minutes left of a final-round match, which the All Blacks won 57-15 to achieve a record victory against the Springboks.
French referee Jerome Garces reacted by yellow-carding the 2015 South African Rugby Player of the Year.
However, after reviewing the incident, the citing commissioner considered the incident had met the red-card threshold for foul play.
When De Jager was sent to the sin bin, New Zealand exploited their numerical superiority to score three converted tries through Codie Taylor, Ben Smith and Liam Squire.
Replacement hooker Taylor was yellow-carded in the final minute for a high tackle.
