More than an inch of rain fell at Kempton over the weekend and, despite racecourse officials emphasising yesterday that the track dries quickly, bookmakers believed that The Fellow may encounter ground too testing for him to show his best form.
Ten horses are expected to line-up against the French horse on Boxing Day as he attempts a record-equalling third successive victory in the race.
Twelve accepted yesterday for the event but one of them, Cool Ground, is expected to run instead in the following day's Welsh National.
Barton Bank, another leading fancy for the King George, also drifted in the betting yesterday. He is now available at 4-1 - and Saturday's impressive Betterware Cup winner Young Hustler, also on offer at 4-1 - may well overtake him as the main home hope.
