Racing: Leading Irish chaser Glencove Marina, at the head of the ante-post betting for both the Arkle and the Royal & SunAlliance Chase, has been ruled out for the season.
Trained by Willie Mullins, the six-year-old sprang to prominence for the Cheltenham Festival events by effortlessly winning a Grade Two novice chase at Leopardstown earlier in the month.
His big-race target had not been finalised and he was earlier handed entries in both championship events before disaster struck.
"He's got a tendon injury and he's definitely out for the season," Mullins told At The Races.
Mullins went on: "We are not sure how long the injury will take, I haven't spoken to our vet who scanned him but he is definitely out for all this season and maybe we'll decide to give next season a miss too.
"He appeared to be fine after Leopardstown because we were checking him every morning.
"He'd had a week off and he was back riding and doing small canters, but we just noticed a little bit of heat on the backside of his leg and was hoping against hope it might have been something else, but it wasn't.
"So we sent him off to get scanned and the vet told us the bad news this morning.
"He was the most exciting horse I've had for years, the potential that he had, he has come out and shown that this year over fences. I was really looking forward to him so it is very disappointing."
