Zaidpour bids to give Willie Mullins a third consecutive success in the Ladbrokes Boyne Hurdle at Navan.
After recording a second Grade One victory at Leopardstown over Christmas, the eight-year-old produced a lacklustre performance when well beaten at Gowran Park last month and arrives with something to prove as a result.
Un Beau Matin was ahead of him in second that day but the biggest threat to Mullins' inmate could come from Bog Warrior.
Tony Martin's gelding is having his first start since finishing a creditable fifth in the World Hurdle at the Cheltenham Festival last March, got the better of Zaidpour in the Galmoy Hurdle the time before and doesn't have many miles on the clock for his age.
The injury-plagued Dunguib is another interesting runner.
Two other Grade Two events feature on the seven-race card, and Foxrock can continue his progression in the Ten Up Novice Chase.
The Ted Walsh-trained prospect proved his promising third in the Grade One Topaz Novice Chase at Leopardstown to be no fluke when landing a Naas Grade Two with ease last month.
The experienced Cootamundra and My Murphy, who was seven lengths behind Foxrock at Leopardstown, will be on hand if the favourite fluffs his lines.

The latter has Ruby Walsh for company but all eyes will be on the former, for whom giving 11lb to Djakadam proved too much last time but he will be a warm order to get back on track here.
Action gets underway at 1.40 with Dunsany Handicap Hurdle, in which Annie Oakley is expected to make a bold bid for a double.
