Equestrian safety rules will be revised for the Beijing Olympics to protect riders from head injuries, the FEI governing body said Friday.
Horse and rider teams will be eliminated from competition after one fall by either in the cross-country or showjumping disciplines. Current rules allow riders a second fall.
"The reason for the change is firstly medical given the difficulty to evaluate the gravity of a fall which can result in a mild concussion," the FEI said in a statement. "A subsequent lapse in judgment exacerbated by a concussion could result in serious injury."
The ruling was approved by the FEI and the International Olympic Committee, and follows a conference on eventing safety held by the federation in Copenhagen, Denmark, in January.
It comes into force on Aug. 1, one week before the games begin. The Olympic equestrian events are being held in Hong Kong rather than Beijing because of quarantine restrictions on mainland China.
