CINCINNATI — Cincinnati linebacker Darryl Blackstock agreed Monday to stay with the Bengals, who have taken two hits to their offense in the first days of free agency.

Blackstock, an unrestricted free agent, started four games last season and appeared in eight others, getting 17 tackles. He was suspended for four games by the NFL for using a performance-enhancing substance.

The Bengals also re-signed defensive lineman Orien Harris, a second-year player who appeared in 14 games last season.

The Bengals have lost right tackle Stacy Andrews, who signed with Philadelphia, and second-string quarterback Ryan Fitzpatrick, who went to Buffalo as a free agent.
