Ravens tight end Todd Heap, who absorbed a big hit to the head at New England on Sunday, sat out practice Wednesday with a sore neck. Starting Ravens safety Tom Zbikowski (foot) didn't practice. Other Ravens starters on the injury report who were limited included: running back Ray Rice (ankle), linebacker Jarret Johnson (back) and receiver Derrick Mason (ankle, finger).
Ravens right tackle Jared Gaither, the subject of much offseason trade speculation, remains out this week due to chronic back issues. Gaither has yet to play this season.
The Bills are expected to have everybody available except Terrence McGee and Cornell Green.
