Saturday's abandoned Stanjames.com Champion Hurdle Trial will not be rescheduled.
BHA spokesman Paul Struthers said on Sunday that the Haydock race, lost to frozen ground, would not be saved because meetings at Ffos Las, Sandown, Kelso and Wincanton offer ample alternatives.
Walkon was among the small field originally scheduled to race at Haydock but a quick change of destination saw the dual Grade 1 winner, returning from a layoff stretching back to April 2009, produce a brilliant performance to finish second in the Bet With Your Mobile At victorchandler.com Holloway's Hurdle at Ascot.
Connections will now consider whether to send the six-year-old direct to the Cheltenham Festival, where he is a general 33-1 chance for the Champion Hurdle, or take in a race in February, with the Totesport Trophy at Newbury a possible target.
Iain Turner, racing manager to Walkon's owner Max McNeill, said: "We'll have a think about whether to go direct to Cheltenham, there are some options in February, but we haven't spoken about options after the race and we were really more concerned that he would get up alright this morning -and he has."
