Cinders And Ashes remains a possible runner in the Stan James Champion Hurdle, but neither Peddlers Cross nor Overturn will be at Cheltenham this year.
Donald McCain's star trio have all been sidelined since last season and only Cinders And Ashes is close to a competitive return.
The 2012 Supreme Novices' Hurdle winner failed to rediscover that level of form in three starts last term and was last seen pulling up in the 2013 Champion.
McCain said: "Cinders is in fast work and is working away grand. I'm not quite sure where we'll start off with him, but I'm happy with him at the moment."
Peddlers Cross is another previous Festival winner and was runner-up behind Hurricane Fly in the 2011 Champion Hurdle, but little has gone right for the nine-year-old since.
He was pulled up on his most recent appearance in last year's World Hurdle.
The admirable Overturn has been a brilliant servant to his connections on the Flat, and over hurdles and fences, but failed to fire in last season's Arkle before finishing second at Aintree's Grand National meeting.
McCain said: "Peddlers is just starting back again. He was in fast work and working really well, but then he had a bit of a setback. I wouldn't think he'll be going to Cheltenham.
"I don't think you'll see Overturn until well into the spring. He had a bit of a niggling injury towards the end of last season and it has just taken him a while to get over it.
"He's a 10-year-old now, but he loves his job and with a horse like him there are obviously plenty of options."
