Durban - The South African Rugby Union (SARU) have confirmed that the reason for the withdrawal of Frans Steyn from the Springboks was due to a contractual disagreement."In light of media coverage following Frans’ request to leave the Springbok squad, we have been placed in a very difficult position," SARU CEO Jurie Roux said."We have an agreement with players in respect of the rights of both employer and employee not to publicly discuss any contractual situation and I will not breach that. "However, allegations have been made that affect the reputation of the South African Rugby Union and Frans Steyn as an employee and person and they cannot go unchallenged."It is alleged that SARU breached a promise to Frans in terms of his contract."I can confirm that there was a dispute over mechanisms by which one element of Frans’ Springbok remuneration was to be paid. "That issue was addressed. "Some minor details remain to be sorted out, but they are not of such a scale as to be a cause for a major upheaval."Out of respect for Frans’ wishes, whatever other considerations may have been on his mind are not for me to discuss. "I look forward to his return to playing in the near future in Super Rugby as he has been a good servant to the Springboks and his franchise."
