Jair Du Cochet put down after leg break Leading Tote Cheltenham Gold Cup candidate Jair Du Cochet has been put down after breaking a leg today. The Guillaume Macaire-trained seven-year-old claimed the scalp of dual Gold Cup winner Best Mate at Huntingdon in November and cemented his big-race claims with success in the Pillar Chase at Cheltenham in January. He had been clear second-favourite for next week´s blue riband.
