Four Ravens players absent from Wednesday's practice

OWINGS MILLS, Md. — Counting down to the home opener against Cincinnati after an extended stay out west, the Ravens were without four key players during Wednesday’s workout.
Left tackle Eugene Monroe (concussion), wide receiver Breshad Perriman (knee), running back Lorenzo Taliaferro (foot), and defensive end Chris Canty (calf) were not present during the portion of practice open to reporters. Head coach John Harbaugh offered no update on Monroe’s progress in recovering from a concussion suffered on the opening drive of the Week 1 loss at Denver.
“I really don’t have any update on a concussion,” Harbaugh said prior to Wednesday’s practice. “It’s never something that you get an update on. He’s in the protocol and he’s working on it right now.”
Making his season debut in Oakland on Sunday, Taliaferro rushed seven times for 34 yards and a touchdown in the 37-33 loss to the Raiders. It remains unclear whether the second-year running back’s injury was to the same foot he hurt last December.
Canty left Sunday’s game with a calf injury and played just 16 defensive snaps. The veteran defensive lineman was available in the locker room after Wednesday’s practice, but he would not commit to being able to play against the Bengals.
“I’m optimistic. I can’t make any promises,” the 32-year-old defensive end said. “The coaches and the medical staff probably would be able to tell you more, but I’m optimistic about the opportunity to be able to be out there. We’ll just see what happens.”
Newly-acquired cornerback Will Davis was taking part in practice on Wednesday and will wear No. 39 for the Ravens. Harbaugh said the organization had liked the 5-foot-11, 190-pound cornerback from Utah State leading into the 2013 draft before Miami selected him in the third-round.
General manager Ozzie Newsome traded a 2016 seventh-round choice to the Dolphins in exchange for Davis.
“He’s a guy who has really good coverage skills we feel like,” Harbaugh said. “With the types of defenses we play, we think he fits us really well, but we’ll find out. We’ll find out by how he plays and how he conducts himself.”
Despite tweaking his knee during Sunday’s loss, inside linebacker C.J. Mosley was taking part in Wednesday’s practice and was not included on the injury report. Cornerback Rashaan Melvin was also removed from the injury report after missing his second straight game with a hamstring ailment that’s hindered him off and on since the beginning of August.
Meanwhile, the Bengals were without two key offensive starters as wide receiver A.J. Green (knee) and left tackle Andrew Whitworth (back) both missed Wednesday’s practice. Safety Reggie Nelson (groin) was a limited participant.
