Starting left guard Kelechi Osemele, who has been dealing with a back injury, was not practicing Wednesday during the Ravens' final workout before they head into the bye week.
Osemele has played in all seven games for the Ravens and Ravens coach John Harbaugh said he's been dealing with the back issue since last year.
Also not practicing for the Ravens were running back Bernard Pierce (hamstring), wide receiver Brandon Stokley (groin) and linebackers Albert McClellan (shoulder) and Josh Bynes (finger infection).
Pierce aggravated the hamstring injury in Sunday's loss to the Pittsburgh Steelers. Bynes missed the game against the Steelers after having surgery last week to remove the infection. Bynes said that he expects to play next Sunday against the Cleveland Browns.
The Ravens won't have to disclose an official injury report until next Wednesday. After today's practice, the Ravens will be off until Monday per rules of the collective bargaining agreement.
