Pro Bowl cornerback Charles Woodson left last weekend's 38-35 victory over the New York Giants with a concussion and is going through the NFL-mandated protocol to receive medical clearance. Packers coach Mike McCarthy said the team's medical staff is optimistic Woodson will be able to play against the Raiders.
Running back James Starks sustained another ankle injury, and his status is unclear, although McCarthy said he didn't expect it to be a long-term issue.
"They're getting better," McCarthy said. "They're getting close."
