Oakland safety Rod Woodson was placed on injured reserve Wednesday with a knee injury, becoming the 11th Raiders player lost for the season and fifth in nine days according to an Associated Press report.
Woodson, who was in his 17th NFL season, had been playing with a sore left knee after having minor surgery Sept. 9 to repair a meniscus tear sustained during training camp.
Woodson, 38, hasn't practiced all season and missed the team's second game against Cincinnati. He will have surgery in the next couple of weeks.
Last week, defensive ends Trace Armstrong and Sam Williams, linebacker Travian Smith and backup running back Justin Fargas went on IR. They joined quarterbacks Rich Gannon and Marques Tuiasosopo, and linebacker Bill Romanowski -- just to name a few.
Woodson played in Oakland's season opener at Tennessee on Sept. 7, then missed the following week's game. After his operation, he played 13 days later at Denver.
"We were all shocked," Raiders head coach Bill Callahan said. "It just shows you the commitment he has to playing. I've never seen anyone like him. It just got to the point it got too sore or too damaged to play on it. I did not know how long he could hang on playing like this. It was unbelievable in every respect. I don't know how he did it."
