The attorney for jockey Martin Pedroza has written to the California Horse Racing Board, asking for information that prompted Santa Anita stewards to suspend the 21-year-old rider for cocaine use.
Sam Silverstein, who represents Pedroza, said that if the response from the board is not satisfactory, the jockey is prepared to file a multimillion-dollar lawsuit.
Before being suspended for 20 calendar days that run through next Monday, Pedroza tested positive twice and negative once for cocaine in state-administered tests.
Silverstein said that two independent tests of Pedroza turned up negative. One of those was done in an Arcadia hospital half an hour after a positive state test, he said.
