Although Haloti Ngata did not practice this week, the defensive tackle is listed as questionable for Sunday's game against the Cincinnati Bengals.
Ngata, who has made 55 consecutive starts in his four-year career, is dealing with a sprained right ankle, but expressed optimism earlier today that he could play Sunday.
Safeties Haruki Nakamura (strained abdominal muscle) and Tom Zbikowski (illness) are also questionable. Nakamura was upgraded today to full participation after being limited Thursday. Zbikowski was limited for the second consecutive day.
Linebackers Jarret Johnson (left shoulder) and Prescott Burgess (illness), tight end Todd Heap (ankle), fullback Le'Ron McClain (shoulder), cornerback Frank Walker (illness) and long snapper Matt Katula (sore elbow) participated fully in practice and are listed as probable.
For the Bengals, strong safety Roy Williams (forearm) was limited in practice and is questionable for Sunday.
Fullback Jeremi Johnson (sprained left knee) was upgraded from limited to full participation and is probable. Defensive tackle Tank Johnson (foot) was added to the injury report after being limited in practice, but he is also listed as probable.
