England head coach Steve Borthwick has highlighted World Rugby’s inconsistent approach to disciplinary issues.

Tom Curry was sent off in the third minute of Saturday’s World Cup victory over Argentina for a dangerous tackle and received a two-match ban, yet similar incidents involving South Africa’s Jesse Kriel and Martin Sigren of Chile failed to produce a dismissal, citing or suspension.

It has raised concerns over the officiating of illegal challenges involving the head.

Borthwick also highlighted that when Owen Farrell was sent off for a dangerous tackle against Wales and then cleared by a disciplinary hearing, World Rugby intervened by appealing against the decision.

“There has been a large amount of commentary from different sources about what appears to be a lack of consistency and transparency in the decision making process,” Borthwick said.

“Now it’s not my role to comment on that, it’s World Rugby’s. I also note there was a tremendous amount of comment from World Rugby on Owen Farrell for a couple of weeks during our preparation for this tournament.

“It was a situation that went on and on with lots of comment from World Rugby. I note there hasn’t been very many comments from World Rugby – I’m told – in the last week or so. I will leave that to World Rugby.”
