Ravens safety Kyle Hamilton did not practice Wednesday but did run on the sideline as he works to recover from the ankle injury he suffered last Thursday against the Cincinnati Bengals.

Hamilton’s status for Sunday’s high-stakes AFC North matchup with the Pittsburgh Steelers is unclear. His absence would be another blow to a Baltimore pass defense that ranks last in the league after giving up 428 yards and four touchdowns to Cincinnati’s Joe Burrow.

Hamilton limped off just before halftime after his ankle buckled. He did not return to the game. Ravens coach John Harbaugh said his Pro Bowl safety avoided a serious ankle injury but that the timeline for his return was unclear. Harbaugh was asked about Hamilton’s progress Wednesday but offered no new information.

Outside linebacker Kyle Van Noy (illness) was the only other Raven absent from practice.

Tight end Isaiah Likely returned as a limited participant after missing the Bengals game with a hamstring injury. Defensive end Brent Urban practiced fully after missing the past two games because of a concussion.

For the Steelers, outside linebacker Alex Highsmith, already ruled out for Sunday by coach Mike Tomlin, was absent as expected, but outside linebacker Nick Herbig was a full participant in Wednesday’s practice as he prepares to return from a hamstring injury. Highsmith has three sacks this season and Herbig has 2 1/2 for a defense that ranks second in the league in scoring, allowing 16.2 points per game.

Running back Najee Harris (ankle), wide receiver Van Jefferson (quadriceps) and cornerback Donte Jackson (hamstring) did not practice Wednesday, though Tomlin has said Jackson and Harris are likely to play against the Ravens. Defensive tackle Cameron Heyward and left guard Isaac Seumalo received an extra day of rest.
