Questions remain at center

The post-practice injury report continued to point today to a first career start Sunday for Ben Wilkerson.

Starting center Rich Braham (knee) was doubtful and did not practice. Backup Eric Ghiaciuc, who sprained his right knee Thursday night against Baltimore, is questionable and did not practice. He had a brace on the right knee over the lunch hour.

Coach Marvin Lewis would not tip his hand about his plans in the middle of the offensive line for Sunday.

Wide receiver Kelley Washington (hamstring) is questionable and did not practice.

Five players were probable, and only safety John Busing (knee) practiced today. The four other probable players who did not practice were defensive tackles Sam Adams (knee), Shaun Smith (illness) and John Thornton (knee) and wide receiver T.J. Houshmandzadeh (back).

For Oakland, wide receiver Jerry Porter (hip) is doubtful, and guard Barry Sims (abdomen) is questionable.
