Three-fourths of the starting secondary was absent from the portion of practice open to the media today. Safeties Ed Reed and Dawan Landry and cornerback Samari Rolle were not present on the practice field behind the team's training facility in Owings Mills.

Coach John Harbaugh said Rolle (neck surgery) and Landry (spinal cord concussion) probably would not be able to play against the Oakland Raiders this Sunday. "There’s a slim chance those two guys could play, but right now, I wouldn’t anticipate it," Harbaugh said.

Cornerback Chris McAlister was present. McAlister played sparingly in the Ravens' 27-13 win against the Miami Dolphins last Sunday, and Harbaugh did not make any promises about starting McAlister against the Raiders.

Wide receivers Demetrius Williams (left Achilles tendon) and Yamon Figurs (left knee contusion) also were not at practice.
