Since then however, Warburton has denied any intended malice but did hold his hands up and say that Rolland made the right decision – a move the Irish official believes will benefit the game.
"To be fair to Sam, I think it is a true measure of the man he is," said Rolland.
"I don't think he had to come out to say anything and I didn't really care one way or the other because what happened, happened.
"I think for the game in general it was a very good comment by Sam because parents looking on would be happy to see he came out and said what he said."
Among the myriad defences for Warburton was that a tip tackle was not intended – but Rolland is adamant he followed the law to the letter.
"The important part for referees is to take the emotion out of it," he added.
"We can only officiate on the action itself and what he did merited what happened next because it was dangerous.
"We don't officiate on intention, we officiate on the action itself.”
