The California Horse Racing Board (CHRB) has filed complaints against trainers Art Sherman and Wesley Ward for medication violations.

The CHRB issues a weekly update of complaints, accusations, stewards rulings, and board decisions involving Class 1, 2, and 3 medication violations and other significant matters.

In the case of Sherman, the Maddy Laboratory at the University of California, Davis, reported that Brahma Bull, a horse trained by Sherman, exceeded the regulatory threshold of 37.0mm1/1 for total carbon dioxide. Brahma Bull finished second in the fourth race at Bay Meadows Dec. 2, 2006.

A TCO2 violation is considered Class III. A hearing has not been scheduled
