Bengals, Williams agree on deal

The Cincinnati Bengals reached a one-year agreement to re-sign safety Roy Williams Saturday, according to his agent, Jordan Woy.

Williams and defensive tackle Tank Johnson were two of the primary free agents on defense the Bengals needed to prevent from leaving in free agency. Johnson signed a four-year deal earlier in the week.

Williams came to the Bengals last season after being let go by the Dallas Cowboys.
