Racing:Uimhiraceathair has been ruled out of next week's RSA Chase at Cheltenham after suffering a setback.
The eight-year-old was due to defend an unbeaten record over fences, having registered successes at Gowran and Navan, and had been as short as 10-1 for the Festival after impressing in a gallop at Leopardstown last month.
However, champion trainer Willie Mullins has confirmed his charge will not be heading to Prestbury Park.
The County Carlow handler said: "He's lame and he's not going to Cheltenham."
