Roy Williams is currently an unrestricted free agent but he's expected to return to Cincinnati, according to Pro Football Talk:
Safety Roy Williams has twice been a free agent, and twice he'll sign with the Bengals. Williams' agent Jordan Woy told the Bengals' team website a deal could be finished by the end of Saturday.
The Bengals said that they wanted to bring back former Cowboys Tank Johnson and Roy Williams and followed through.
The former Cowboy played in just four games last season after fracturing his forearm on November 13.
