HIGH-class filly Somehow has been put down after fracturing a cannon bone.

Aidan O'Brien's four-year-old won five of her 12 starts including the Group 2 Dahlia Stakes at Newmarket in May.

She was last seen filling the runner-up spot to Decorated Knight in the Group 1 Tattersalls Gold Cup at the Curragh.

O'Brien said: " Unfortunately Somehow has suffered a fatal injury. She got a fracture behind on her cannon bone and we were unable to fix it.

"It's a real pity as she was such a good filly, and had progressed well this season."
