After failing to sign free-agent offensive linemen Derrick Dockery and Daniel Loper, the Lions turned to one of their own Thursday, re-signing guard Damion Cook.

Cook played in seven games and made four starts at left guard last year. The Lions will continue searching for competition at that position and could add a player in the draft, but Cook is at least a stop-gap measure who can play multiple positions.

Edwin Mulitalo, who shared the starting duties with Cook last year, was released last month.

Free-agent guard Derrick Dockery, released by the Bills on Thursday, is at the Lions' Allen Park facility meeting with team officials right now. Dockery and receiver Nate Washington of the Steelers are the only two free agents expected to visit with the Lions today. It's possible the Lions could sign one or both before they leave, with Dockery being the more likely of the two to sign.

Dockery, by the way, is a massive individual. He would start immediately at left guard and upgrade the Lions' offensive line immensely. He turns 29 in September.
