Springbok prop Thomas du Toit will serve a six-week ban reduced to three weeks for the red card he received for a high tackle on Luke Cowan-Dickie in South Africa's 27-13 win over England.
His suspension will see him miss his side Sharks' first Champions Cup matches against English outfit Harlequins and Top 14 team Bordeaux-Begles in what is the first season South African franchises are to compete in the competition.
In a separate case, France captain Antoine Dupont is free to play for his club Toulouse in their Top 14 match this weekend after he won his appeal against a four-week suspension for his red card in the win over South Africa.
The 26-year-old scrumhalf missed France's final Autumn Nations Series Test - the 35-17 victory over Japan - and Toulouse's 21-14 defeat to Lyon last Sunday.
