O'Brien referred after Dante victory

Aidan O’Brien was referred to the British Horseracing Authority after reportedly refusing to allow raceday officials to examine Cape Blanco following his win in the totesport Dante Stakes at York.

The Ballydoyle trainer watched from County Tipperary as Cape Blanco galloped to second-favouritism for the Investec Derby, after which rumours circulated about his well-being.
