IF Cheltenham's Festival Trials Day goes ahead, it will not feature Gold Cup ante-post favourite Bobs Worth.
Nicky Henderson's charge will bypass the Argento Chase after he was found to be not quite 100pc following a routine check-up. The eight-year-old will now contest the Gold Cup on March 15 without a prep run.
"We were scoping him and there was a little something there," Henderson explained. "It's not wise to run at the weekend if he's not going to perform to his best."
Tidal Bay is also reported to be a doubtful runner, with trainer Paul Nicholls describing him as "slightly lame" and "odds against" to run.
Cheltenham are "extremely hopeful" tomorrow's Trials Day meeting will go ahead as planned.
Staff at Prestbury Park have been battling the elements all week as they try to get the track ready for a meeting which is set to feature Sprinter Sacre in the rearranged Victor Chandler Chase.
While the track has been covered for over a week to guard against frost, snow had looked a problem as it was lying on top of the covers.
An 8.0 inspection was planned for this morning, but officials are optimistic. Tomorrow's meeting at Doncaster has been abandoned due to snow, as has Sedgefield on Sunday.
Meanwhile, Peddlers Cross will face classy performers Salden Licht and Sam Winner in one of today's Jumpers' Bumpers at Kempton.
Donald McCain's 2011 Champion Hurdle runner-up has been ready to run for some weeks now but has been repeatedly thwarted by the weather.
With a chasing campaign on hold, McCain is trying to get him ready for either the Champion Hurdle or the World Hurdle in March, but the Aintree Hurdle at the Grand National meeting is also in the mix.
"He's unbeaten first time out but this is slightly different," said McCain. "He'll get a good surface to race on, he's in good order at home and it's time to crack on with him."
