Laurel Race Course canceled its card yesterday after the forecast of warmer weather failed to materialize, leaving icy conditions.

After an inspection of the racing surface by jockeys and track officials, it was agreed that track conditions would make racing hazardous.

Alberto Delgado, Laurel's leading rider, said: "Our representatives met with us and we felt that the cushion of the track was fine but that the icy condition underneath would cause clods of ice and mud to be flying all over the place.

"The horses would be exposed to eye injury and even the jockeys with goggles on would be in danger . . . We felt that it wasn't right for anybody to race under those conditions."

Laurel owner Frank DeFrancis said: "All our forecasts were for weather in the 40-degree range. At 7 a.m., it was 27 degrees and expected to go up. At 11 a.m., it was 26 and apparently getting colder. The parking lots were icy and the starting gate was having trouble with the ice, so we got together with the riders and decided to call off the card."

The cancellation was the sixth of the Laurel meeting, including one card during which only four races were run. DeFrancis said Laurel would make up the lost days during its fall meeting, which will begin on Oct. 3.

Laurel intends to run every day through its final program, scheduled for Feb. 16, and will run 10 races each Saturday and Sunday through that date.

The weather also caused cancellation of the racing cards at Aqueduct (N.Y.) and at Philadelphia Park. Charles Town (W. Va.), which has not run a full card since last Saturday, also was forced to scrap its card.
