Vikings running back Onterrio Smith, who has a history of violating the NFL's substance-abuse policy, was briefly detained by airport police last month after they found an elaborate kit used to beat drug tests. Police at the Minneapolis-St. Paul International Airport questioned Smith on April 21 after a search of his bag discovered vials of white powder, according to a police report. Smith told officers it was dried urine used in conjunction with a device called "The Original Whizzinator." The officer who filed the report wrote that Smith "told me that it was dried urine for making a clean urine test." In addition, he had a bottle of pills labeled "cleansing formula." Smith told police he was taking the vials to his cousin. The police report didn't say where Smith was traveling. The Star Tribune first reported the story Wednesday. "We will continue to monitor the situation as we would with any other and evaluate it from there," coach Mike Tice said in a statement Wednesday.
