Paul Nolan’s giant staying chaser was considered a major contender as he went in search of his third Grade One prize, but he trailed home seventh of the nine runners.
Nolan initially thought the drying ground might have been partly to blame for his disappointing display, but a subsequent scan revealed a serious injury.
“We had the horse scanned this morning and it has shown he has a 10% hole in a hind tendon,” said the Wexford-based trainer.
“We now have a valid reason for his lacklustre performance in the Lexus, but, unfortunately, it means the horse is out for the season.
“Straight after the race we thought the ground hadn’t helped him, but he’s a Grade One-winning chaser and considering he was beaten going to the first fence, there had to be more to it than that.
“To be honest, I’ve only feared running him on better ground because he is such a big horse.
“He’s worked on better ground and worked fine, so I had a fair idea it couldn’t have just been the ground the other day.
“He was in trouble from the very first fence, so the injury must have happened running down to that.
“It’s a serious injury, but it could have been worse, and we’ll just have to give him some time now and see where we are.
“It’s very disappointing as I was so looking forward to the season with him, but I’d be hopeful he’ll be back for next season.
“Hopefully we can look at running the John Durkan (Memorial Punchestown Chase) and the Lexus again.”
Nolan, meanwhile, is considering the plan of attack with Noble Prince following another excellent effort in defeat at Leopardstown last week.
The eight-year-old landed the inaugural Jewson Novices’ Chase at last season’s Cheltenham Festival and a return to Prestbury Park for the Ryanair Chase is very much on his agenda.
He has been running with credit over shorter distances so far this season, winning at Naas and chasing home Big Zeb twice, most recently in Leopardstown’s Paddy Power Dial-A-Bet Chase.
“He’s finished second again but we were delighted with the run and obviously he is going to benefit from a step up in trip again,” said Nolan.
“Having said that, Tony (McCoy) got off him the other day and said it would also have suited him better if they’d gone a faster pace.
“In the two-mile conditions races in Ireland they don’t seem to go as fast as they do in England, and that doesn’t really help him.
“The Ryanair Chase will be his target — that will be his only entry at Cheltenham.
“I’ll have a chat with the owner in the next couple of days and decide whether he’s going to run again before Cheltenham and if he is, where that will be.
“There are options for him over all sorts of different trips, so I’ll have a chat with the owner and see which way we’re going to go.”
