The Ravens continue to have an uncommonly clean sheet of health for mid-December. They’ll face a Steelers team that isn’t as fortunate leading into the rivalry showdown Saturday afternoon at M&T Bank Stadium that will help decide the AFC North division title.

Wide receiver Nelson Agholor was Baltimore’s lone surprise nonparticipant. According to the injury report, which was a practice estimation for Tuesday’s walk-through, he is in the concussion protocol. Agholor caught his only target for 26 yards in Sunday’s win over the New York Giants — his first catch since Week 10 vs. Cincinnati.

Diontae Johnson will not practice this week having been excused from team activities following his one-game suspension. Cornerback Jalyn Armour-Davis (hamstring) did not practice. Coach John Harbaugh said Monday it was a soft-tissue injury that happened before Sunday’s game against the Giants but it’s “not too serious.”

Safety Ar’Darius Washington (ankle) was limited but appeared to move around the locker room without issue. Rookies Sanoussi Kane (hamstring) and Adisa Isaac (hamstring) were limited, too. Cornerback T.J. Tampa (ankle) was listed but was a full go.

Pittsburgh had seven players, including six starters, absent from their practice Tuesday.

Linebacker and former Raven Patrick Queen (rest), wide receiver George Pickens (hamstring), safety DeShon Elliott (hamstring), cornerback Donte Jackson (back), linebacker T.J. Watt (ankle) and defensive lineman Cameron Heyward (rest) were all out for the first practice of the week. Fellow starting defensive lineman Larry Ogunjobi (groin) was limited. And backup quarterback Justin Fields, whom the Steelers have used in specific packages since Russell Wilson claimed the starting job, was absent Tuesday because of an abdominal injury.

Watt missing Saturday’s contest would be the biggest blow for Pittsburgh, which has bested Baltimore in eight of the past nine meetings.

The outside linebacker exited in the fourth quarter of Sunday’s loss to the Eagles with a low ankle injury. That came after recording two sacks and a forced fumble. Watt told reporters on Tuesday he’s in “wait-and-see mode” for Saturday’s game. Coach Mike Tomlin added he was walking around the facility “rather comfortably” and is optimistic the star pass rusher who is third in the NFL with 11 1/2 sacks can play.

As for the rest of Pittsburgh’s absences, Tomlin told local reporters he’ll “formulate a plan for having increased participation from those guys over the course of the week.”

Like the Ravens managing three games in 11 days, the Steelers are on a short-week schedule facing Baltimore then Kansas City in an 11-day span.
