A furious Kieran O’Neill was given the all-clear to resume riding on Wednesday, having been prevented from taking his rides at Southwell on Tuesday in an incident which has put the British Horseracing Authority’s [BHA] trial of saliva and sweat testing in the spotlight.

O’Neill had three mounts booked at the Nottinghamshire track’s evening meeting, but was unable to take part after being stood down by the BHA following a failed saliva test.
