Show jumper Andrew Bourns led a clean sweep for Ireland in Sunday’s $50,000 Hermès Derby at the FTI Winter Equestrian Festival in Florida.

Showjumping Ireland is to investigate the serious injury of Deirdre Bourns, mother of international showjumper Andrew Bourns, after she was struck by a horse at Cavan Equestrian Centre Indoor Championships on Wednesday.

Ireland’s show jumpers battled to second place in the world’s richest nations cup on a superb weekend that saw their compatriots pick up medals at the European Junior Eventing Championships and in the pentathlon at the Junior World Championships.

Three Irish riders were in the prize money at last night's World Cup Grand Prix in Wellington, Florida, but it was Britain's Scott Brash who took victory with Sanctos Van Het Gravenhof in an 11-horse jump off.
