Rival D'Estruval (right): Misses rest of season
Pauline Robson's stable star Rival D'Estruval has been ruled out for the rest of the season due to a back problem.
The nine-year-old was one of the leading contenders for the National Hunt Chase at last year's Cheltenham Festival and looked set to take a hand in the finish until parting company with leading Irish amateur Derek O'Connor two fences from home.
He disappointingly pulled up when favourite for the Scottish Grand National on his next appearance and on his only start this term, he finished last of five in a graduation chase at Haydock last month.
Rival D'Estruval remains towards the top of ante-post lists for the Foxhunter Chase at Prestbury Park next month, but Robson's partner and assistant David Parker has revealed he will not be returning to the Festival.
Parker said: "He is going to Newmarket later this week for an operation on his back, so he won't be going to Cheltenham and he won't run again this season.
"He's had quite serious problems with a kissing spine, which is why he has lost his form, unfortunately.
"Hopefully it will be sorted out later this week and we'll look forward to getting him back on track next season."
