Bengals keep vital part of offensive line, sign Williams

Cincinnati Bengals guard Bobbie Williams will sign his two-year deal on Friday, according to a league source.

Williams recently agreed to a new contract worth roughly $2.85 million per season. He is a key member of that offense and played at a Pro Bowl level in 2009 as the Bengals won the AFC North.

The signing of Williams -- who was the NFL's top-rated free-agent guard, according to NFL.com's Pat Kirwan -- means that the Bengals could have the same starting offensive line on back-to-back opening weekends for the first time in four years.
