SAN FRANCISCO —  "Sugar" Shane Mosley is accusing convicted steroids dealer Victor Conte of slander for telling newspapers he saw the boxer knowingly inject steroids.

Mosley filed suit against Conte in federal court, accusing the founder of the Bay Area Laboratory Co-Operative of making the allegedly false statements to boost book sales. Conte is planning to write a book about the steroids scandal now enveloping sports.

Conte says he stands by the comments he made to the newspapers.

Mosley, a former three-division world champion, has said he unwittingly used steroids produced by BALCO.
