Rod Woodson undergoes surgery on left knee
The 38-year-old Woodson was hurt in the Raiders' 25-20 season-opening loss at Tennessee on Sunday. Coach Bill Callahan wasn't sure Wednesday how long his leader of the secondary would be sidelined.
"It was a new injury during the game," Callahan said. "It should be day-to-day, week-to-week. Historically, he's been a fast healer."
