Sienna Myson-Davies (pictured) will miss out on defending her junior European eventing title because her ride Tambourine is injured.

A statement from the 17-year-old said that Tambourine sustained a tendon injury in the field last weekend. A vet scan on Monday confirmed the injury and a further scan in the coming weeks will ascertain the severity of it. The nine-year-old gelding is expected to be out of competition for the remainder of the season.

Sienna said: “Obviously I am devastated to miss the Europeans as we were on form and I was really looking forward to it, but I am relieved that ‘Tambo’ hasn’t sustained a long term injury and we will be back competing together next season.”

Sienna is replaced on the squad for the championships at Waragem, Belgium (11-14 September) by Dani Evans, 17, with Heather Sheppard’s Uchin.

The loss of Sienna — a double gold medallist at last year’s junior Europeans, as well as the final trial winner this time — will be a blow to the squad, but Dani has consistent form, including fifth as an individual at last year’s championships and fourth at Houghton CCI* this spring.
