Ravens free safety Ed Reed rejoined his teammates at practice Thursday as he was upgraded to limited participation after sitting out the previous day.
While Reed deals with a knee injury and a torn labrum in his shoulder, four other starters were sidelined for the second consecutive day.
Pro Bowl defensive tackle Haloti Ngata (right shoulder, right knee) didn't practice as well as defensive end Pernell McPhee (thigh, right knee), offensive guard Bobbie Williams (left ankle) and Pro Bowl offensive guard Marshal Yanda (right knee).
Williams predicted he would play Sunday.
"I'm feeling well, and I expect to be out there," Williams said. "I'm going to keep getting better, getting the ankle right and doing what we can. I'm just going to take a day today."
Besides Reed, the following players were limited again: cornerback Jimmy Smith (groin), wide receiver David Reed (knee), offensive tackle Michael Oher (ankle), wide receiver Jacoby Jones (toe) and linebacker Josh Bynes (thigh).

Offensive tackle Khalif Barnes (groin), tight end Brandon Myers (shoulder), kicker Sebastian Janikowski (left groin) and safety Matt Giordano (hamstring) were limited.
