Hot favourite Un De Sceaux will face nine rivals in the Betway Queen Mother Champion Chase at Cheltenham.
Last year's brilliant Arkle hero is odds-on across the board to provide Willie Mullins with his first win in the two-mile showpiece and comes up against three former winners in Nicky Henderson's Sprinter Sacre, Gary Moore's stable star Sire De Grugy and the Paul Nicholls-trained Dodging Bullets.
Mullins also runs Felix Yonger, but has withdrawn Gold Cup contender Vautour and rank outsider Twinlight.
Henry de Bromhead saddles Special Tiara, while former stablemate Sizing Granite makes his first start since joining Colm Murphy.
God's Own, Just Cameron and Somersby complete the field.
