With a 2007 linebacker corps that couldn’t stay healthy and Landon Johnson defecting for Carolina, the Cincinnati Bengals have agreed to terms with free-agent linebacker Darryl Blackstock, according to Geoff Hobson of Bengals.com.

Blackstock was a third-round draft pick of the Arizona Cardinals in 2005.  The Cardinals opted not to utilize the one-year restricted free agency tender on Blackstock, making him an unrestricted free agent even though he has only three years of service.

He played college football at Virginia with Ahmad Brooks, who was selected by the Bengals in the third round of the 2006 supplemental draft.
