Ante-post favourite Rolling Star features among 58 entries for the JCB Triumph Hurdle at Cheltenham on 15 March.
The French import leapt to the head of the market for the four-year-old championship when making an impressive British debut for Nicky Henderson on Festival Trials Day at Cheltenham on Saturday.
The Seven Barrows trainer has won the Triumph Hurdle five times and his other entries are Alexandre Six, Courtesy Call, Megalypos and Vasco du Ronceray.
Irish Saint, runner-up to Rolling Star at Cheltenham, is among six possibles from the Paul Nicholls stable. They also include dual course winner Far West, currently second favourite in the ante-post market.
The 15 Irish contenders are headed by Our Conor, trained by Dessie Hughes, and Diakali, who is one of seven engaged for Willie Mullins.
