Defensive tackle Haloti Ngata did not practice for the second consecutive day. It's beginning to look increasingly doubtful that Ngata, who is dealing with a sprained right ankle and was absent from the the portion of practice open to the media, will be available Sunday against the Cincinnati Bengals.
Long snapper Matt Katula (sore elbow) also missed his second straight day of practice. As mentioned earlier, there is no backup to Katula listed on the team's depth chart.
Cornerback Frank Walker (illness) and linebacker Prescott Burgess (illness) did not practice Wednesday, but returned to full participation today. Linebacker Jarret Johnson (left shoulder) also practiced fully.
Safeties Haruki Nakamura (strained abdominal muscle) and Tom Zbikowski (illness) were upgraded to limited participation after sitting out Wednesday's session. Tight end Todd Heap (ankle) and fullback Le'Ron McClain (shoulder) were limited for the second consecutive day.
.For the Bengals, strong safety Roy Williams (forearm) and fullback Jeremi Johnson (sprained left knee) were limited for the second straight day.
