Updating the Steelers-Dolphins preview: Rookie DT Derrick Harmon's absence continues to hurt Pittsburgh's run defense, while Miami adds depth with LB Quinton Bell amid their four-game win streak.
Building on the Week 15 preview amid mounting injuries like T.J. Watt's lung issue, rookie DT Derrick Harmon remains sidelined for his third straight game (fifth overall) with a knee injury, impacting Pittsburgh's run defense, which has surrendered 191.3 rushing yards per game in his four absences—including 217+ in the last two. Harmon, with 22 tackles, four QB hits, two sacks, and one pass deflection this season, eyes a Week 16 return vs. Detroit.
RB Jaylen Warren is active despite illness, bolstering the offense. Pittsburgh (7-6) hosts streaking Miami (6-7) at frigid Acrisure Stadium (8:15 p.m. ET, ~22°F), where the Dolphins are 0-13 under 40°F.
Miami bolsters its roster: signing LB Quinton Bell (7th-rounder, 2019; 1 tackle in 3 games this year) to the active roster, elevating OT Kion Smith from practice squad, and waiving LB Andre Carter II. De'Von Achane (90+ rush yards in each of four straight wins) is expected despite ribs. Steelers are 3-point favorites (O/U 42.5); win keeps them atop AFC North.
