Cape Town - Worcester Warriors want compensation for an injury sustained by Francois Hougaard while on Test duty with the Springboks.
Hougaard, who played for the Boks in several Tests during the Rugby Championship, returned to Worcester with a shoulder injury.
The scrum-half was set to be sidelined for three months due to the injury and his recovery is ahead of schedule but the Warriors' chief executive, Jim O'Toole, is adament that his club wants to be paid for the player's setback.
"Francois Hougaard came back from South Africa carrying an injury which he suffered during his campaign with them and we've had to pick up the pieces from that," he told the BBC.
"It has been disappointing to lose one of your top players, and one of your highest paid players too, for such a long period.
"He's a freak of nature, in terms of his rehabilitation, and we're hoping he's back a little bit earlier than originally anticipated.
"But we're working with our friends at the South African Rugby Union and World Rugby under 'regulation nine' to make sure that we get compensation."
