Tomlin said Harmon and wide receiver Brandon Johnson (foot) will be evaluated more in the coming days. Tomlin did not give a timetable for their return.
When asked if the team is worried that Harmon might have suffered serious ligament damage, Tomlin said “like I said, it is a knee sprain.”
It didn't look good for Harmon right away.
His knee twisted awkwardly as he was engaged with a blocker on a pass rush. He was in tears with a towel over his head as he rode on the back of a cart to the locker room.
The former Michigan State and Oregon player was the 21st pick in April.
The Steelers elected to start a handful of starters on both sides of the ball against the Panthers, including Harmon. The rookie had been expected to start this season on a defensive line with Cameron Hayward and Keeanu Benton.
Veteran Isaiahh Loudermilk is expected to see more playing time if Harmon is out a significant amount of time.
The Panthers did not play their starters.
