After missing the previous three games with right knee and thigh injuries, starting left defensive end Pernell McPhee practiced for the second consecutive day on a limited basis.
McPhee underwent a pair of arthroscopic knee surgeries prior to training camp, which has limited his production to a half-sack after recording six sacks as a rookie last season.
"I'm getting better, I'm getting my feet back under me," McPhee said. "I'm doing all the easy stuff on the field, but coach [John] Harbaugh will make the decision on whether I'm out there Sunday."
