Rugby’s world governing body has asked Six Nations organisers to explain the decision not to punish England prop Joe Marler for his “Gypsy boy” comment.
Marler made the comment to Wales prop Samson Lee, who is from the Traveller community, during England’s Six Nations win at Twickenham on Saturday.
The Welsh Rugby Union said it was “surprised” Marler was not sanctioned.
Verbal abuse of a player based on ethnic origin can carry a minimum sanction of a four-week suspension.
In a statement Six Nations Rugby said it was “aware of the seriousness of Mr Marler’s comment and does not in anyway condone what was said” but accepted it was said “in the heat of the moment”.
World Rugby said in a statement that “in accordance with its regulations”, it has requested further information from the Six Nations, “in respect of the process that led to its decision.”
