Johannesburg - Springbok front rowers Dean Greyling and Werner Kruger have extended their contracts with the Bulls until the end of the 2015 season, the Pretoria union announced on Tuesday.
"It is no secret that high quality props are hard to keep in the country and to have two of them agreeing to an extension of three years at the same time is wonderful news, not only to the Bulls, but also to South Africa," said Bulls head coach Frans Ludeke.
"Both Werner and Dean have their best years in their positions still ahead of them and to know that they will be playing those in South Africa, and more particularly Pretoria, is awesome news for all concerned."
