The Ravens' wide receiver corps took a step in the right direction Thursday with the return of Zay Flowers to the practice field. Flowers is dealing with a foot issue that left him limited after sitting out Wednesday.
Odell Beckham Jr. did not practice for a second straight day due to illness, however.
Beckham and the Ravens have an extra day to get healthy this week since they're playing on "Monday Night Football" in San Francisco.
Right tackle Morgan Moses and cornerback Ronald Darby also returned to practice. Left tackle Ronnie Stanley (concussion) and safety Marcus Williams (groin) were limited.
Cornerback Jalyn Armour-Davis (concussion) was the only player other than Beckham who did not practice.
The 49ers have a lengthier injury report. Defensive tackle Arik Armstead (foot/knee) and defensive tackle Javon Hargrave (hamstring) did not practice. The 49ers had nine players who either sat out or were limited Thursday.
