One-time Epsom Derby favourite High Definition bids to get his career back on track in the Group 3 Alleged Stakes at the Curragh on Sunday.
The Aidan O'Brien-trained four-year-old impressed with two wins, including a Group 2 success in the Beresford Stakes, and was one of the expected leading lights at three last year.
He failed to fulfil those expectations, though, finishing third in the Dante on his return and trailing in 10th of 11 when favourite for the Irish Derby.
Two more defeats followed in the Great Voltigeur and St Leger and he drops back in trip to 1m2f for his reappearance this weekend.
O'Brien said: "He seems in good form and is ready to start back. He'll improve for the run. He might just have been a bit weak last season and it's possible that having a second run at two wasn't ideal in hindsight.
"We're happy with him and looking forward to running him."
Likely dangers include last year's Tattersalls Gold Cup winner Helvic Dream and Jason The Militant, who is better known for his hurdling exploits but is 2-2 on the Flat.
High Definition, who is 2-3 at the Curragh, has multiple big-race entries for this season, including in the Yorkshire Cup, Tattersalls Gold Cup and Coronation Cup.
O'Brien has won three of the last four runnings of the Alleged Stakes with Capri (2018), Magical (2019) and Broome last year. Other victories with Black Sam Bellamy, Brian Boru and Dylan Thomas make him the most successful trainer in the race's history.
