Special Tiara and Fox Norton, first and second in the Queen Mother Champion Chase, are on course to clash again in Sunday's Shloer Chase at Cheltenham.
The Henry de Bromhead-trained Special Tiara enjoyed his finest hour at the Festival back in March and has been third in this race twice before, including when beaten 18 lengths behind Colin Tizzard's winner Fox Norton last year.
Cloudy Dream could run after being forced to miss his intended outing in the BetVictor Gold Cup.
Malcolm Jefferson's grey was a leading ante-post fancy for Saturday's main event but was a surprise omission from the list following Monday's confirmation stage.
Jefferson's daughter Ruth has taken responsibility for the mistake as he instead ended up with an entry in the three-mile-three-furlong BetVictor Handicap Chase, which precedes the feature race.
"We've put him in the Shloer on Sunday as that has been reopened," said Mick Meagher, racing manager to owner Trevor Hemmings.
"Ruth was supposed to confirm him for the BetVictor Gold Cup Handicap Chase and he's actually ended up in the BetVictor Handicap Chase, the race before.
"It's human error, it will happen again, but we'll kick on.
"We'll make a decision on whether he runs later in the week, but that is where we are at. He's fully entitled to run in that, he was second in the Arkle."
Simply Ned, Josses Hill, Top Gamble, Sizing Granite, Sir Valentino, Vaniteux, Oliver's Dream and Somchine are the other possibles.
