Pressure is mounting on leading golfing bodies to investigate New Zealand caddy Steve Williams after his racial insult aimed at Tiger Woods caused worldwide revulsion.
Williams sparked outrage with the slur after he collected an award during a caddies' gala dinner in China this weekend.
Williams has posted an online apology to Woods but the players' casual reaction and silence from the sport's leading officials has been seen as a closing of ranks - and anti-racist groups have lined up to condemn the European and PGA Tours for failing to censure Williams.
