TAMPA, Fla. (AP) -Receiver David Boston was released by the Tampa Bay Buccaneers on Wednesday, two days after police released results of a urine test that showed the eighth-year pro had a depressant in his system when he was arrested and charged with driving under the influence last month.

The Bucs said Boston, who hurt his foot during pregame warmups and did not play in last Sunday's season opener at Seattle, was let go after reaching an injury settlement. Receiver/kick returner Mark Jones was signed to replace him.

Boston was arrested Aug. 23 when police said he was found slumped over the steering wheel of a red Range Rover with the SUV running and in drive.

A breath test taken at the scene was negative for alcohol, however the receiver also submitted a urine sample that was tested for other substances.

Police said Monday that an initial positive reading for GHB, or gamma hydroxybutyric acid, was verified by a second independent lab. GHB is a central nervous system depressant often called the ``date-rape drug'' because it leaves people groggy and powerless. Among other things, it is also said to have body-building effects.

Last week, the 29-year-old receiver issued a statement through the team saying he had done nothing wrong and was not impaired when he was arrested.

Boston, who has also played for Arizona, San Diego and Miami, missed most of the past three seasons because of knee injuries. He also was suspended four games in 2004 for violating the NFL's steroid policy.Copyright © 2005 The Associated Press. All rights reserved.
