Ireland's Bertram Allen has lost an appeal against his disqualification from the Olympia Grand Prix.
Allen, 20, had posted a stunning jump-off time of 30.45 seconds on Quiet Easy to destroy a world-class field at the London International Horse Show.
But blood was subsequently found on Quiet Easy's right flank, prompting Allen's disqualification by the ground jury under article 242.3.1 of the FEI Jumping Rules.
An appeal was lodged on Allen's behalf but, after speaking to the ground jury, the FEI steward and the appointed representative of the rider, the appeal committee upheld the decision.
The class was subsequently awarded to Brtain's Michael Whitaker, riding Viking, a statement on the Olympia website confirmed. Germans Ludger Beerbaum and Marcus Ehning were second and third.
