Willie Mullins’ Hurricane Fly is one of 14 entries for the BHP Insurance Irish Champion Hurdle at Leopardstown on 29 January.
The champion trainer could also be represented by Thousand Stars, Zaidpour and So Young.
Hurricane Fly, winner of the Festival Hurdle at Leopardstown over Christmas, will be bidding to land the race for a third successive year.
Binocular and Grandouet could line-up for Nicky Henderson.
Binocular has yet to reappear this season after returning to training later than many of his stablemates and with Henderson having so many Champion Hurdle contenders this season, this race has been mentioned as a possible starting point.
Grandouet, forced to miss the Cheltenham Festival in March through a late setback, made a pleasing return to action in last month's International Hurdle against Zarkandar and Rock On Ruby.
John Quinn's Countrywide Flame, an easy winner of the Fighting Fifth Hurdle at Newcastle but well beaten in the Christmas hurdle at Kempton, is another possible challenger from Britain.
Solwhit, an established rival of Hurricane Fly who made such an encouraging reappearance for Charles Byrnes recently, could take on his old foe once more. Byrnes has also entered last year's smart novice Trifolium.
Ladbroke winner Cause Of Causes, Captain Cee Bee, Unaccompanied and Hisaabaat complete the list.
