Show jumper Denis Lynch will not represent Ireland in the Olympics,.
His nomination was dramatically withdrawn today by Horse Sport Ireland following a meeting in Dublin with the Tipperary rider.
Lynch was selected only last week as one of two show jumpers, including Corkman Billy Twomey, to participate in London 2012.
However, HSI was forced to request that the Olympic Council of Ireland (OCI) pause the German-based rider’s ratification after his top horse, Lantinus, was disqualified from competition at Aachen, Germany, on Friday morning, after vets deemed the gelding's legs were hypersensitive.
It was the third time for a horse ridden by Lynch to come under the spotlight in terms of hypersensitivity in the past 12 months.
In 2008, Lynch was disqualified from the Olympics just before the final after Lantinus tested positive for the banned substance capsaicin.
HSI is expected to release a statement soon, but the governing body is not due to announce until tomorrow who will be Lynch's replacement, with Cian O'Connor or Cork's US-based Shane Sweetnam the main contenders.
Denis Lynch has the right to appeal today's decision.
