BECAUSEICOULDNTSEE, which was as short as 10/1 with the sponsors for the Ladbrokes Irish Grand National, will not run in next Monday's Fairyhouse showpiece.
Connections blamed a poor build-up to the English Grand National for the eight-year-old's second-fence exit at Aintree and have decided to call time on his season.
Trainer Noel Glynn said: "He didn't get a clear run to the Grand National and was too fresh. We'll put him out now and bring him back for the Paddy Power Chase at Leopardstown next Christmas then go back to Aintree for the Grand National."
Becauseicouldntsee finished second in this term's Paddy Power Chase, a race in which he sustained the injury to a hind leg that disrupted his preparation.
Majestic Concorde, who unseated Robbie McNamara at the Canal Turn in the English National, will also miss the Fairyhouse equivalent, but trainer Dermot Weld has confirmed Prince Erik for the contest.
"Majestic Concorde has recovered from Aintree, but he won't run in the Ladbrokes Irish National or at Punchestown. He will either go for the Chester Cup, in which he ran fourth last year, or on a few months' holiday," said Weld.
With the going currently good after a spell of dry weather, and with no rain on the horizon, officials began watering the course yesterday in an effort to provide safe ground.
