OWINGS MILLS, Md. (AP)Lamar Jackson will miss a fourth straight game for the Baltimore Ravens because of his knee injury.

The Ravens on Friday ruled out Jackson for Sunday night’s game against Pittsburgh. The Ravens have already clinched a playoff spot but trail Cincinnati by a game for first place in the AFC North.

Baltimore also ruled out cornerback Marcus Peters because of an injured calf. Defensive end Calais Campbell, who has been dealing with a knee injury, returned to practice Friday but was limited. He’s listed as questionable.

Safety Geno Stone (hamstring) and tight end Nick Boyle (illness) are also questionable.
