Crusaders captain Scott Barrett has been hit with a four week suspension following his red card in last Friday's defeat to the Blues.
Barrett was shown a red card in the 46th minute the Super Rugby Pacific clash after making clear contact with his shoulder to the jaw of Alex Hodgman.
In other suspensions, Highlanders lock Josh Dickson has been dismissed for three weeks after getting red-carded for an early hit on Tevita Mafileo in their loss to the Hurricanes at Dunedin.
Hurricanes hooker Asafo Aumua has also been banned for three weeks for making head contact in the same game.
