London 2012 Olympics: Irish show jumper Denis Lynch dropped from Games squad amid drug fears The monitoring has been controversial. Last year at the Rolex World Cup finals in Geneva, overnight leader McLain Ward of the US was disqualified when his horse Sapphire failed a sensitivity test, even though she did not test positive to any banned or controlled substance. Lantinus had not been named as Lynch's nominated Olympic ride. In a statement Lynch said: "While a small wound on the left foreleg and an abrasion on the right hindleg sustained in the previous days" competition were identified, these were not associated with any hypersensitivity or abnormalities in the thermographic examination. Lantinus was re-examined again after competing in both rounds on Thursday and again on Friday morning at 8.30am. In summary, the areas of sensitivity highlighted above on the left forelimb and on the hind limbs had increased after Lantinus had competed. We were advised that Lantinus was now considered hypersensitive within FEI Veterinary Regulations and Lantinus was disqualified by the attending FEI vets. At no stage, was there any inference that the hypersensitivity was anything other than natural occurring. I feel this is very important to clarify and I would also like to state for the record that I fully support all measures regarding hypersensitivity implemented by the FEI. US-based Shane Sweetnam or Cian O'Connor are the likely replacements, though O'Connor himself was disqualified from the individual gold medal position at Athens 2004 after his horse tested positive to sedatives.
