Dr. David Chao is the target of the investigation after one player was arrested on suspicion of possessing controlled substances, Vicodin , 100 tablets in his car. No hearing has been set and it seems to me this is standards procedure as sports players could get the medication from other doctors as well. The doctor could face 
losing his license depending on the outcome. BD
As a federal drug investigation that involves the San Diego Chargers and San Diego Padres continues, the state medical board's attempt to revoke the medical license of the Chargers' team doctor has gained renewed attention.
The National Football League's Chargers and Major League Baseball's Padres said they are fully cooperating with the Drug Enforcement Administration investigation, in which agents served 10 search warrants Tuesday on physicians and pharmacies affiliated with the teams.
Tuesday's actions came after former Chargers safety Kevin Ellison was arrested in Redondo Beach in May on suspicion of possessing a controlled substance after police said they found 100 Vicodin tablets in his car. Ellison was recently released by the Chargers and signed by the Seattle Seahawks.
In a statement, the Chargers said that "the Vicodin in Kevin's possession was not provided by the Chargers, its physicians or anyone affiliated with the team."
