If the appeal is denied, Williams would be one more positive test away from a four-game suspension. Williams declined to talk about the issue this week, saying he wasn't allowed to talk about it.
-- The news was more positive when it came to Ogunleye, who got a long-term contract offer from the Dolphins.

-- The Dolphins signed wide receiver Willie Johnson, a rookie free agent from Nevada who had been invited to the post-draft minicamp.
-- Former Dolphins wide receiver James McKnight has signed with the New York Giants.
