After Lamar Jackson went down with a knee injury on Dec. 4, Ravens coach John Harbaugh said he considered his star quarterback “week-to-week.”

But with Jackson missing his 13th straight practice Wednesday, he’s now been sidelined for exactly a month, casting doubt on his availability for Sunday’s regular-season finale against the Cincinnati Bengals and perhaps the postseason.

Harbaugh said Monday that he didn’t know whether Jackson would return to practice this week, but that he hoped Jackson would return in time for the postseason. Backup Tyler Huntley, who has started since Week 14, going 2-2 in that span despite a limited passing game, was limited in practice Wednesday by right (throwing) shoulder and wrist injuries.

“Whichever quarterback plays, that’s the quarterback that’s going to play, and we’ll expect them to play great football,” Harbaugh said Monday.

The Ravens had hoped to enter Week 18 with a chance of winning the AFC North title and securing a home game in the wild-card round of the AFC playoffs. But the NFL’s suspension of Monday’s Cincinnati Bengals-Buffalo Bills game in the wake of safety Damar Hamlin’s cardiac arrest has muddled their playoff picture.

Cornerback Marcus Peters, who’s missed the Ravens’ past two games with a calf injury, returned to practice Wednesday. Harbaugh said Monday that Peters and defensive lineman Calais Campbell (rest/knee), who returned to practice last week after a Week 15 injury but was not present Wednesday, have a “chance” of playing Sunday.

Also missing Wednesday were offensive linemen Ronnie Stanley (rest) and Kevin Zeitler (rest), running back J.K. Dobbins (rest), wide receiver DeSean Jackson (illness) and outside linebacker Justin Houston (rest). Cornerback Kevon Seymour (finger) was limited.

Bengals defensive end Sam Hubbard (calf) was the only player listed on Cincinnati’s injury report Wednesday.
