If England bothered with tackling practice, Charlie Ewels must have been absent for the lesson.
Mathieu Raynal had barely got proceedings under way when Ewels, with not a thought to technique, smashed head-to-head into James Ryan. It was an unequivocal red card, but what a terrible moment for the Irish player. He has accumulated a frightening number of brain injuries, and it was distressing to see him leave the field. There will be very real questions for Ryan and his medical advisers; top of the list is bound to be how many serious knocks to the head are enough.
