CINCINNATI (AP) -- Bengals right guard Bobbie Williams has been suspended for the first four games of the season because he violated the NFL's policy on performance enhancing substances.

The 12-year veteran has started all 16 games each of the last four seasons. It'll be the first time since 2003 with Philadelphia that he missed four games in a season.

Coach Marvin Lewis said the team was aware of the pending suspension. Williams won't be allowed to work out with the team until the fifth week of the season.
