Steelers lose a pair of defensive anchors to high-ankle sprains, risking a two-week lull just before a bye. Loudermilk and Highsmith are sidelined, with Herbig back to stabilize the line and Black and Lee stepping in for Loudermilk. Harmon’s return remains uncertain, while the Steelers must navigate a road test at New England. Key early-game injuries and depth-chart shuffles define Pittsburgh’s short-term outlook as they chase depth and scheme tweaks.
