According to Sirius Satellite Radios Howard Balzer, Bills defensive end Anthony Hargrove has failed his second drug test. As a result, Hargrove will have to sit out the entire 2008 NFL season. Balzer made the report late Saturday night. So far, the Bills have not commented. Hargrove was suspended for the first four games of 2007 after his first positive drug test. Hargrove is a free agent. If the Bills werent planning to re-sign him, the suspension wont affect Buffalo. However, if Hargrove was in Buffalos plans, he probably wont be anymore.
