I see Byrnes the Younger received a 21 day ban from the stewards earlier this week:

It looks like he was penalised under the dangerous riding rule. The stewards report states he “rode in a way which was far below that of a competent and careful rider”.
Have the Irish authorities finally grown a spine and had enough of this gruesome operation? Even if we accept the official explanation that he did not jump off at Wexford last year, it should have been possible to say that ride was incompetent as well.
