TORRANCE, Calif. (AP) — Seattle Seahawks safety Kevin Ellison has pleaded not guilty to drug possession in Southern California.

Ellison entered the plea Wednesday in Los Angeles County Superior Court in Torrance. He remains free on $10,000 bail.

The 23-year-old Ellison was released by the San Diego Chargers after he was pulled over for speeding by police in Redondo Beach on May 24. He was arrested after officers allegedly found he had about 100 Vicodin pills but no prescription for the painkiller.

The arrest has prompted a Drug Enforcement Administration investigation of a doctor on the Chargers' medical staff. The doctor and the team have said that Ellison didn't obtain Vicodin from team contacts.

The Seahawks claimed Ellison off waivers after he was released by San Diego.
