NEW YORK (AP) — An NFL lineman who lost his starting job while serving a doping suspension filed a lawsuit against the league in federal court Wednesday, claiming it knew the weight-loss supplement StarCaps contained a banned substance but didn't tell players.

Jamar Nesbit is an 11-year veteran who lost his starting job with the New Orleans Saints in 2008 when he chose to serve a four-game suspension after testing positive for bumetanide.

Nesbit says he took StarCaps, which didn't list bumetanide as an ingredient.

Like a couple of Vikings players who were caught in the same situation, Nesbit contends that NFL officials knew StarCaps contained bumetanide, but did not specifically notify players or the U.S. Food and Drug Administration.
