Dolphins running back Ricky Williams has failed an NFL drug test and could be facing a one year or longer ban from the league.http://www.miami.com/mld/miamiherald/13921386.htm"After testing positive for marijuana in three previous NFL drug tests, Dolphins running back Ricky Williams tested positive again, but this time the banned substance is not marijuana, according to sources.
That was the latest bizarre twist in the player's on-going saga -- a saga that apparently is not over.
Two sources said the running back, who faces a minimum one-year ban from the league, has appealed his latest positive test in hopes of continuing his career.
"I would be blown away if Ricky Williams used drugs," said agent Leigh Steinberg, who represents Williams. "And that's how most of the people around him also feel."
Even if that is true and Williams has not been using street drugs, it would not preclude him testing positive for a banned substance. The NFL has a list of nearly a dozen so-called supplements that are banned. Even too much water in a urine sample can trigger a positive test result because it can be deemed a masking agent for drugs."
