I thought, if the players have to go through this process, why not referees? That wasn’t accepted by the board. I think, at that particular time, it was just rejected as, ‘It doesn’t happen to referees’.
"We have started to discuss this and this is something for the future which will be discussed to possibly include an anti-doping programme for referees. We do not have an indication that this is a problem but this is something we have to look at. The referees are a neglected population."
