Brian Boru, winner of last season’s Seabiscuit St Leger at Doncaster, heads a field of eight in the Alleged Stakes at Leopardstown on Sunday.
The Aidan O’Brien-trained colt drops back to a mile and a quarter for the first time since he finished third to Alamshar and The Great Gatsby on his first run as a three-year-old over the same course last May.
Brian Boru is O’Brien’s only runner from a four-strong entry in the Listed contest.
The son of Sadler’s Wells has to give 3lb or 7lb to his seven rivals, who are headed by Jim Bolger's Napper Tandy, who was a short head behind him in fourth in last May’s race.
Akshar, formerly trained by Michael Stoute, has his first outing since he joined Dermot Weld’s team.
O’Brien introduces an impeccably bred three-year-old filly in the Ashmount Maiden over a mile and a quarter.
All Too Beautiful, a full sister to 2001 English and Irish Derby winner Galileo, has six rivals in the mile-and-a-quarter contest.
