Former winners Albertas Run and Riverside Theatre are among 27 remaining entries for the Ryanair Chase at the Cheltenham Festival on March 14.
Along with Riverside Theatre, Seven Barrows maestro Nicky Henderson could call upon last year's Champion Chase hero Finian's Rainbow.
Leading Gold Cup contender Sir Des Champs, owned by Ryanair proprietor Michael O'Leary, still has this option, as does First Lieutenant in the same ownership.
Sizing Europe, another former winner of the Champion Chase, could run over the extra distance this season, while Rubi Light and Prince De Beauchene are other strong Irish hopes.
Tom George's Mail De Bievre showed up well for a long way in the Denman Chase and could be suited by a drop in trip, while Cue Card's Festival destination is likely to be decided after he runs this weekend.
Grands Crus, Champion Court, Menorah and Wishfull Thinking are others who remain in contention.
Among the 12 scratchings were Bog Warrior, Flemenstar and Unioniste.
