Although Carl Davis sat out his second consecutive day of practice because of a hamstring injury, the Ravens defensive tackle said he still hopes to play Sunday when the Chicago Bears visit M&T Bank Stadium.
"I'm in the playbook," he said. "The game of football at this level is about knowledge and knowing mentally what you're doing and what your opponent is doing. Definitely practice plays a big portion of it, but that's what we have training camp for – to learn the playbook and be able to gain that muscle memory. So I don't think I could lose that muscle memory in a couple days. But I would definitely like to be at practice. So we'll see."
In addition to Davis, four other players sat out for a second straight day: defensive tackle Brandon Williams (left foot), right guard Matt Skura (sprained right knee), cornerback Jimmy Smith (Achilles tendon) and running back Terrance West (left calf).
Rookie outside linebacker Tim Williams joined them as a nonparticipant. He had been listed as limited Wednesday because of a thigh injury.
Earning the limited designation for the second day in a row were defensive backs Anthony Levine Sr. (thigh) and Jaylen Hill (hamstring), and wide receiver Jeremy Maclin (shoulder).
Tight end Maxx Williams, who has sat out the past three games because of a left foot injury, practiced fully, as did wide receiver Breshad Perriman. Perriman said he took the advice of the training staff and sat out Wednesday's session to allow his knee to heal.
"I just got hit wrong [on Sunday], and that was it," he said. "There was nothing more to it. It wasn't anything serious at all. Just took a day off to let it calm down, and now I'm fine."
Chicago practiced Thursday without starting right guard Kyle Long (ankle). Starting cornerback Marcus Cooper Sr. (back) was upgraded to limited participation after missing Wednesday's session. Starting inside linebacker Nick Kwiatkoski (chest) was limited for the second straight day.
End zone: Harbaugh, a former special teams coordinator, might have gotten a bit of enjoyment from watching Chicago pull off a fake punt that resulted in a 38-yard touchdown pass from punter Pat O'Donnell to running back Benny Cunningham in the third quarter Monday against the Vikings. But it also caught his attention from a scouting standpoint. "You feel like, 'OK, they're not going to go run that one again unless we just hand it to them, which we shouldn't do,'" Harbaugh said. "And I think it speaks to the mindset that they have in terms of they're going to pull out the stops that they think they need to [in order] to win the game. So it broadens your thinking in terms of what they may do against you. So you've got to be looking for all of those types of things from all three phases." … The Ravens signed rookie offensive tackle Dieugot Joseph to the practice squad after releasing him Tuesday. The team made room for him by waiving rookie center Derrick Nelson.
