Rambo (knee) did not practice Wednesday, ESPN.com reports.

EDGE Analysis

Rambo has been working through the knee issue for most of December. He missed practice last Wednesday and still played against the Cowboys, where he saw action on 58 defensive snaps and logged three tackles. Rambo is seeing starter's time amid all the injuries to the Buffalo safety unit, though Corey Graham is the guy you want to own if you have the choice.
