The Browns worked out Hanie last week, but decided to sign Alex Tanney off Dallas' practice squad. Tanney backed up Weeden on Sunday against Jacksonville. Weeden was diagnosed with a concussion following the loss to the Jaguars and is following the NFL's program for head injuries.
Hanie gives the Browns another option as a starter this week against the Patriots. Coach Rob Chudzinski may choose to start him over Tanney because he has started four regular-season games.
Campbell sustained a concussion last week against Pittsburgh. He has been cleared for football activities but not practice.
