Show jumper Denis Lynch has so far refused to comment on today's dramatic decision to withdraw his Olympics nomination.
His nomination was dramatically withdrawn today by Horse Sport Ireland following a meeting in Dublin with the Tipperary rider.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.
An obviously upset Lynch said: "I do not want to talk" as he waited for a flight back to Germany after today's decision. His brother Shay said they had not ruled out an appeal.
"Denis is devastated," he said. "It's been his goal to get to London, having secured a spot for Ireland. All his thoughts were geared towards this and all his dreams came crashing down today.
"We are considering an appeal, but as there is no appeal process in place, which we find unususal, we are waiting until HSI revert to us."
Shay Lynch added the brothers had not discussed taking legal action, as they are waiting until any possible appeal process has been finalised.
HSI was forced to request that the Olympic Council of Ireland (OCI) pause the German-based rider’s ratification following the disqualification from competition of his top horse, Lantinus, at Aachen, Germany, on Friday morning, after vets deemed the gelding's legs were hypersensitive.
HSI said it will likely be tomorrow before it announces Lynch's replacement, with Cian O'Connor or Cork's US-based Shane Sweetnam the main contenders. Ireland manager Robert Splaine will make the selection.
The Aachen disqualification 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.
