Two Ravens defensive starters, safety Jaylinn Hawkins (knee) and outside linebacker Tavius Robinson (pectoral), were not at the start of practice again Friday, putting their availability for the key AFC North game further in doubt.
Robinson, who leads the Ravens with 3.5 sacks, hasn't practiced all week. If he's out, the Ravens would lean more on Mike Green and rookies Zion Young and Ethan Burke.
Hawkins was limited Wednesday but sidelined Thursday. If he doesn't play against the Bengals, the Ravens could plug in second-year safety Keondre Jackson, who hasn't taken a defensive snap yet this season, or shuffle their secondary and move Kyle Hamilton off the line of scrimmage.
