Don Cossack’s racing career in jeopardy after tendon injury

Cheltenham Gold Cup winner Don Cossack’s racing career could be in jeopardy after he suffered a tendon injury which rules him out of the Punchestown Festival.

The brilliant nine-year-old was due to line up in the Bibby Financial Services Ireland Punchestown Gold Cup on Wednesday, but will play no part in the big spring Festival.

Don Cossack’s problem was discovered on Sunday morning once the Gigginstown House Stud-owned chaser returned from a workout on the gallops.
