OZONE PARK, N.Y. – Horsemen were both surprised and upset when the final eight races of Saturday’s card at Aqueduct were canceled by the jockeys because of concerns over poor visibility due to fog.

After running the first race under foggy conditions – and over a sealed, sloppy track – the riders met prior to the start of the second race, though five of the seven horses in the paddock were tacked up. After a brief meeting, the riders informed the stewards that they did not want to ride the remainder of the card.

As a result, the quarantine that the Pennsylvania Department of Agriculture imposed on Nov. 13 has been lifted.
