Saru has called an urgent meeting for Monday to determine the accuracy of the reports with Western Province, the player's contracting union, and the University of Cape Town Rugby Club, where the statements were said to have been made.
SA Rugby's manager of national teams and acting managing director, Andy Marinos said that if the reports were accurate, it was a very serious matter.
He said: "We can't pre-judge the matter on the strength of media reports and we can make no definitive statement until we have in our hands what evidence there may be.
Marinos said a further statement would be issued following the meeting with Western Province and UCT.
