Wales and England have shown rare rugby unity in the aftermath of their Six Nations stoush at Twickenham.
England prop Joe Marler provoked his opposite Samson Lee with a "Gypsy boy" slur which was picked up by the television microphones as the frontrowers squared off in a push and shove scuffle.
Marler apologised to Lee at halftime for his insult and coaches from both sides admonished Marler for his insult while World Rugby and Six Nations officials are investigating.
"I think as players and coaches, there is banter in the game, and I think there is no place for that," Rob Howley, the Welsh skills coach said.
"I think Samson is the best person you can ask about that. I think he had a fairly different take on it. As far as we are concerned, there is no room in the game for that.
"This is the first time in my experience of being involved with international rugby that it has happened. I am sure World Rugby will decide, effectively, what to do, and we will support them in whatever that decision is."
Marler was cited after the test for elbowing an opponent in England's 25-21 victory and faces a judicial hearing this week while the inquiry into the "Gypsy Boy" slur continues.
