A day after missing Thursday's practice with a back ailment, starting outside linebacker Jarret Johnson returned to Friday's session.
Prior to practice, Johnson downplayed the severity of the injury, saying, "It's just something that I've had to deal with during my career. I just get them. But it's no big deal."
Johnson has played in 118 consecutive games, which ranks as the longest streak in Ravens history and the fourth-longest active streak in the NFL.
Cornerbacks Chris Carr and Jimmy Smith were both present for the second straight day. Both players were limited Thursday.
The news was not so good for starting strong safety Tom Zbikowski, who was absent from the portion of Friday's session open to the media.
Zbikowski, who practiced on a limited basis Thursday, has been dealing with symptoms stemming from the concussion he sustained in the Ravens' 34-17 victory over the New York Jets on Oct. 2. As of Thursday, he had not yet been cleared for contact, according to coach John Harbaugh.
Others who were not present included starting wide receiver Lee Evans (left ankle), starting left guard Ben Grubbs (strained ligaments in right toe), inside linebacker Dannell Ellerbe (hamstring) and rookie running back Anthony Allen (thigh).
Ellerbe and Allen have already been ruled out for Monday night's contest against the Jacksonville Jaguars.
