The Ravens returned from Sunday's 13-7 win against the Buffalo Bills with several players missing from Wednesday morning's practice open to the media.
Inside linebacker C.J. Mosley, center Jeremy Zuttah, wide receiver Breshad Perriman, and outside linebackers Elvis Dumervil and Za'Darius Smith were not present during the session. The team had not reported any injuries after Sunday's game.
It's unclear why Perriman, who caught one pass for 35 yards against the Bills, is sitting out. The organization's first-round draft pick in 2015 is coming off a year when he overcame a partially torn posterior cruciate ligament in his right knee and a partially torn anterior cruciate ligament in his left knee.
Dumervil did not play on Sunday because of a setback related to his offseason foot surgery, and Smith battled an ankle ailment in the preseason.
Cornerback Jerraud Powers returned to practice. Powers, who did not play Sunday due to an ankle injury, had not participated in practice since the team's second game of the preseason on Aug. 20.
