Gavin Cromwell's Flooring Porter will face 10 rivals as he bids to win the Paddy Power Stayers' Hurdle at Cheltenham on Thursday for the third time.
He has already joined the likes of Galmoy and Baracouda as a dual victor in the race and a third triumph would emulate Inglis Drever, although the indomitable Big Buck's stands alone having won the race four times.
Flooring Porter has suffered an interrupted preparation this year but Cromwell has been pleased with his progress in recent weeks.
Gordon Elliott's Teahupoo is one of the young pretenders aiming to take his crown.
He caused a shock when downing Honeysuckle in the Hatton's Grace and then proved his stamina in the Galmoy Hurdle.
Joseph O'Brien's Home By The Lee was sixth in the race 12 months ago and has improved this term to win the Lismullen Hurdle and Christmas Hurdle at Leopardstown.

Sire Du Berlais and Ashdale Bob also represent Ireland.
The home team is consists of just two, previous winner Paisley Park and Jeremy Scott's Dashel Drasher.

Shishkin will face eight rivals as he goes for a third Festival win in Thursday's Ryanair Chase.
Nicky Henderson's charge landed the Supreme Novices' Hurdle in 2020 and followed up in the Arkle over fences the following year, but 2022 ended in disappointment as he was pulled up when sent off favourite for the Champion Chase.
A rare bone condition was blamed for that defeat and after an initial lacklustre return in the Tingle Creek, Shishkin took a switch up to two miles and five furlongs in his stride when blazing home by 16 lengths in the Ascot Chase last month.
Shishkin is a short price for the extended two-and-a-half-mile Ryanair, but he faces a stern test headed by the Willie Mullins-trained Blue Lord, who forms part of a triple Closutton assault along with Chacun Pour Soi and Janidil.
Envoi Allen represents Henry de Bromhead while the Gordon Elliott-trained Fury Road and Mouse Morris' French Dynamite round out the Irish challenge.

James Du Berlais came home a distant last that day but tries his luck again for Mullins, who also has Appreciate It in contention.
Banbridge is a leading contender for Joseph O'Brien as Henderson's Balco Coastal and Stage Star for Nicholls head the home defence. Christopher Wood, Notlongtillmay and Unexpected Party complete the field.

The Jack de Bromhead Mares' Novices' Hurdle has attracted a top-class line-up, with key names including Luccia, Lot Of Joy and Group One Flat winner Princess Zoe. However, Ashroe Diamond did not feature among the 21 declarations.
The race is run in memory of Henry de Bromhead's son, and the trainer mounts a strong challenge with no less than five contenders, spearheaded by Magical Zoe.
