Derrick Harmon tore into Pittsburgh’s preseason headlines with a knee sprain that could sideline him after a scary exit in Carolina. Tomlin labeled it a knee sprain with no timetable, while Harmon and Brandon Johnson (foot) were set to be evaluated in the coming days. Harmon was slated to start beside Cameron Heyward and Keeanu Benton; if sidelined, Isaiahh Loudermilk and Benton would carry bigger workloads on the Steelers’ defensive line. Carolina rested its starters, leaving depth-chart questions for Pittsburgh going forward. Fantasy players should monitor practice reports for snap counts and potential streaming options on the DL.
