Eddie Jones believes the incident involving Dylan Hartley would have only been a penalty 12 months ago after the Northampton captain was red-carded for an open-arm high tackle on Sean O'Brien.
The England head coach was being interviewed by World Cup winner Clive Woodward for the Daily Mail.
Speaking about the incident Jones said: "I honestly think if he made that tackle 12 months ago it would have been a penalty, but my point was that you have got to be able to adjust to the new rules.
"Make a loose tackle now, you are going to get a yellow card and maybe red. Make a bad call under the high ball and you are going to get a six to eight-week ban. You must adapt to the new game and very quickly," he added.

O'Brien was taken from the field and was unable to return after Hartley hit him high. The Engalnd captain was banned for six weeks.
