The California Horse Racing Board issued a complaint against trainer Gary Jones, whose 3-year-old colt, Capel, tested positive twice for a prohibited painkiller after running fifth in a $36,000 race at Del Mar last month.

The racing board identified the drug as dezocine. The board has referred the case to the stewards at Fairplex Park and a hearing is expected to be held for Jones, who ranks eighth nationally in purses this year with $3.3 million.

Jones has been out of the country and unavailable for comment. Allen Paulson, the owner of Capel, said Sunday that he believes Jones and his veterinarian, Steven Allday, are not responsible for the use of the drug.
