Ravens wide receiver Torrey Smith missed a second straight practice with a sprained right knee, casting his availability for Sunday's game against the Jacksonville Jaguars into further doubt.
Smith, who hasn't missed a game in four NFL seasons, also sat out two practices last week before returning to practice Friday. He then started against the Miami Dolphins, but played just 15 snaps while clearly favoring his knee.
The Ravens seem likely to give him some time to heal, which could lead to rookie Michael Campanaro being active for the first time since Oct.26.
Running back Lorenzo Taliaferro (foot) and tight end Crockett Gillmore (back) also remained out of practice and could miss Sunday's game. If Taliaferro can't play, as expected, the Ravens have the option of activating running back Fitzgerald Toussaint from the practice squad.
Offensive tackle Jah Reid (hand) was a limited participant in practice. His hand was heavily wrapped, but he downplayed the injury. Anthony Levine cleared concussion protocol and was a full participant at practice.
Veterans Steve Smith, Owen Daniels and Daryl Smith were given routine days off from practice.
For the Jaguars, defensive end Chris Clemons (knee) did not practice and was added to the injury report. Defensive end Alan Branch (groin) and linebacker Khairi Fortt (hamstring) also were sidelined.
