Bengals re-sign Tank Johnson

The Cincinnati Bengals retained free agent defensive tackle Tank Johnson on Monday. According to ESPN's John Clayton, Johnson agreed to a four-year contract.

Johnson started 13 games for Cincinnati last season and recorded 29 tackles and two sacks. He helped turn the Bengals' defense into one of the top units in the NFL last season.

The Bengals were the last AFC North team to make a signing or trade since the free-agent period began last Friday, but they likely aren't done. Cincinnati also has been linked with several big-name receivers recently, including Antonio Bryant, Terrell Owens and Brandon Marshall.
