AUBURN — An up-and-coming professional boxer from Maine who’s also the son of a former world champion has pleaded not guilty to drug charges.

Steven Gamache pleaded not guilty Thursday in Androscoggin County Superior Court to a charge of unlawful possession of a scheduled drug.

Authorities say during a routine traffic stop in Auburn in November, an officer found the 29-year-old Gamache in possession of two hydrocodone pills for which he did not have a prescription.

The Sun Journal reports that police said Gamache told them a co-worker gave him the pills to treat an unspecified medical condition.

Gamache was allowed to remain free on $300 bail.

Gamache is 4-0. His father is Joey Gamache, a former World Boxing Association lightweight and super featherweight world champion.
