LONDON -- The Court of Arbitration for Sport says it expects to rule on a selection dispute in Ireland's Olympic equestrian team on Saturday.
CAS says rider Denis Lynch has challenged Horse Sport Ireland's nomination of Cian O'Connor in a two-rider team in individual jumping. The competition begins on Aug. 4 at Greenwich Park.
Lynch was originally selected and then withdrawn after his horse, Lantinus, was disqualified from a recent event on health grounds.
O'Connor won gold in jumping at the 2004 Athens Olympics but was stripped of his medal after his horse tested positive for a banned substance.
Lynch and Lantinus were disqualified at the 2008 Beijing Olympics for using a banned medication.
Lynch's appeal is the third case registered by CAS at its Olympic court.
