Pat Valenzuela's scheduled hearing Wednesday before the Hollywood Park stewards was postponed and no new meeting is scheduled.
Valenzuela, who hasn't ridden since Nov. 2, underwent a medical examination last Friday, and the results were to have been sent to the California Horse Racing Board, then to the stewards. But CHRB Executive Secretary Dennis Hutcheson told the stewards the doctor's report had not been completed.
According to steward Tom Ward, Hutcheson said the board will schedule a hearing with the stewards when all of the documents regarding Valenzuela have been received.
Valenzuela, 28, was suspended indefinitely last month after he called in sick on Nov. 3 at Santa Anita. Late last year, he was suspended for 60 days after testing positive for cocaine.
