LOS ANGELES—Former Raiders quarterback JaMarcus Russell is currently in a Los Angeles Police Department bathroom failing a drug test, records will confirm Wednesday when the urine sample undergoes its initial toxicology screening. "I don't even know why I'm doing this. I'm totally clean now," Russell said moments ago from behind a closed bathroom-stall door while excreting urea containing high levels of marijuana, OxyContin, cocaine, and methamphetamine. "This is total bullshit, I'm telling you. Ah, shoot! Damn it, my shoes… Hey, man, can you slip me some paper towels? Got a bit of a situation in here." At press time, Russell asked to take the test again after purchasing a bottle of Gatorade he was trying to conceal in his left jacket pocket.
