Ravens cornerback Jimmy Smith was not practicing in the portion of Friday's practice open to the media. Smith wasn't on the field early in last Friday's practice, but was ultimately listed as a limited participant.
Running back Lorenzo Taliaferro (thigh), tight end Crockett Gillmore (thigh), offensive guard Alex Lewis (ankle) and cornerback Asa Jackson (undisclosed) also weren't on the field for the Ravens' walk-through practice.
Gillmore, who has missed three consecutive games, had practiced on a limited basis Wednesday and Thursday. It's unclear if he had a setback or the team just doesn't feel he'll be ready in time to face the Bengals.
Taliaferro and Lewis are both expected to miss Sunday's game.
