For the second day in a row, starting nose tackle Brandon Williams was at Ravens practice. But for the second day in a row, he was not participating.
Williams, who missed Sunday's 44-7 loss to the Jacksonville Jaguars in London because of a foot injury suffered the week before, stretched, but did little else during the portion of practice open to the media Thursday afternoon.
Tight ends Benjamin Watson (left calf) and Maxx Williams (left ankle) and rookie cornerback Jaylen Hill (hamstring) were absent from practice. None of the three participated in Wednesday's session.
A pair of Pittsburgh starters in wide receiver Martavis Bryant (illness) and left guard Ramon Foster (thumb) sat out their second consecutive day of practice.

Two starters in strong safety Sean Davis (ankle) and free safety Michael Mitchell (hamstring) practiced on a limited basis after being held out on Wednesday.
Running back Le'Veon Bell (noninjury) and quarterback Ben Roethlisberger (noninjury) were upgraded to full participation after sitting out Wednesday's session. Two more starters in defensive end Stephon Tuitt (biceps) and rookie outside linebacker T.J. Watt (groin) practiced fully for the second straight day.
