Douvan is one of eight entries for the Racing Post Novice Chase at Leopardstown on Saturday.
Last season's Supreme Novices' Hurdle hero won on his chasing debut at Navan in November and is one of three possible runners for Willie Mullins.
The County Carlow handler could also be represented by Net D'Ecosse and Outlander.
Ttebbob has impressed in two starts over fences and could give Douvan most to think about from the Jessica Harrington stables.
Supreme third Sizing John should not be discounted, either, having looked pretty sleek en route to an eight-length defeat of Lord Scoundrel in a Grade Two at Punchestown last month.
Sizing John could be joined in the line-up by fellow Henry de Bromhead inmate Sizing Codelco.
Gordon Elliott may give Lord Scoundrel the chance to set the record straight, while Alan Fleming's Velvet Maker rounds out the list of possible runners.
Meanwhile, Un De Sceaux headlines 11 possibles for the Paddy Power 'So Quick So Easy App' Chase on Sunday.
The Willie Mullins-trained seven-year-old was forced to miss his intended reappearance in the Tingle Creek Chase at Sandown earlier this month, with his handler describing him as a "little flat" in the days before the race.
Mullins also has the King George-bound Vautour engaged, together with Felix Yonger, who recently won the Hilly Way Chase at Navan.
Clarcam and Bright New Dawn represent Gordon Elliott, with Henry de Bromhead double-handed through Sizing Granite and Smashing.
A host of familiar names look set for the Grade One showpiece - formerly known as the Dial-A-Bet Chase - including the Nicky Richards-trained Simply Ned and Shark Hanlon's Hidden Cyclone, who has finished runner-up for the last two years.
Former star two-miler Flemenstar (Anthony Curran) and evergreen veteran Rubi Light (Robbie Hennessy) complete the field.
