Racing:Leopardstown remain "very hopeful" that Sea The Stars will run in Saturday's Tattersalls Irish Champion Chase.
The big clash with Fame And Glory was put in doubt by rain on Monday and an unsettled forecast for the rest of the week.
John Oxx is unwilling to risk his brilliant colt on ground worse than good although he has hinted he may run on good to yielding.
Tom Burke, racing manager at Leopardstown, told At The Races: "We are still very hopeful Sea The Stars will run but Wednesday will be a crucial day weather wise.
"We have the forecast of rain and it depends on how much it delivers us. At the moment we are good to yielding, good in places after six millimetres on Monday.
"Tuesday is a mix of sunshine and showers, but nothing serious. There is then rain on Wednesday but Thursday and Friday don't look too bad."
