Rolland delivered the caution of the tournament start on Friday, telling teams that the number of sin bins and send-offs would be determined by players, rather than officials.
England coach Eddie Jones has been outspoken on the topic, describing as “ridiculous” the red card shown to All Blacks lock Scott Barrett for a dangerous tackle on Wallabies skipper Michael Hooper last month in Perth.
Australian Jones said the sending off “lacked common sense” and was inconsistent with how other similar incidents had been handled this year.
