ANDRE Joubert will remain with the Natal Sharks for, at least, the remainder of the current Currie Cup season, the Natal Rugby Union announced in a statement on Tuesday. “Joubert’s experience is seen as a tremendous asset and a possibility of being called up by Nick Mallett for the Tri-Nations and the World Cup is not ruled out,” the union said. “Joubert is a valuable member of the Sharks and we wish him the best of luck. This could be the final hurdle of a great rugby career.”
