Sharks keep their twins
The twins, loose forwards Jean-Luc du Preez and Daniel du Preez, as well as talented flyhalf Garth April have all extended their contracts until the end of 2018.
The twins, sons of Sharks assistant coach Robert du Preez, have been linked to a move to Europe in recent weeks.
However, Thursday's announcement puts and end to the speculation.
"This is a significant statement of intent on all sides," Gary Gold, Director of Rugby, said.
"Jean-Luc, Dan and Garth have all made outstanding progress during the past few months, and there is not a franchise in Super Rugby or a club in Europe that would not want them in their squad.
"Their decision to remain in Durban, to be part of the new generation team that is fast emerging, will be greeted with delight by everybody associated with The Sharks."
