Steelers Get Promising News On Derrick Harmon's Return From Injury

The Pittsburgh Steelers did not make a trade before Tuesday's deadline, but their next defensive reinforcement could come from inside the building. Derrick Harmon is taking an important step toward returning from injured reserve. For a team trying to strengthen its roster for the second half, getting the young defensive lineman back would give Pittsburgh something the trade market did not deliver.

Head Coach Mike McCarthy said Wednesday that the Steelers are opening Harmon's 21-day practice window, according to Ray Fittipaldo of the Pittsburgh Post-Gazette. That starts the process of evaluating him on the field before a potential activation. It also gives fans a concrete development after weeks of waiting for encouraging news about his recovery.

Harmon remains on injured reserve, so this announcement does not mean he has been cleared to play Sunday. His practice work will help determine how quickly the next step becomes realistic. Fittipaldo shared McCarthy's update on X, explaining that the defensive lineman was expected to participate in some capacity Wednesday afternoon.

"Mike McCarthy said the Steelers are opening the 21-day window to return from IR for Derrick Harmon. He will go through practice in some capacity this afternoon," Fittipaldo wrote.

The timing naturally connects this development to the deadline conversation. Fans who wanted Omar Khan to add help watched the trade window close without an acquisition. Now, the Steelers have a chance to recover a player they already expected to contribute, although getting healthier and successfully addressing every roster concern are separate accomplishments.

Harmon has been sidelined since suffering a foot injury against the Cleveland Browns in early October. It was a frustrating setback for the Steelers' 2025 first-round pick, who was trying to take another step forward in his second season. Now, getting back on the practice field gives him a chance to work his way back into a defense that could use him down the stretch.

There is still plenty to like about the possibility. Defensive line depth becomes especially valuable when a game demands repeated physical snaps, and another available contributor can give coaches more flexibility with their rotation. A healthy Harmon could help Pittsburgh distribute that work without asking the same players to absorb every demanding series.

That benefit does not require an immediate sack or a highlight that spreads across social media. Holding position against a block, maintaining an assignment and allowing teammates to execute can all matter. For a young lineman coming off an injury, dependable snaps would be a useful starting point before anyone demands a breakout performance.

Steelers' Great Harmon Development Comes With A Clear Test

The next meaningful update will concern how Harmon responds to football activity. There is a difference between progressing through rehabilitation and stacking practices against NFL competition. Pittsburgh needs evidence that he can handle those demands before turning an encouraging Wednesday announcement into expectations for Sunday.

The Steelers also should resist treating his potential return as an answer to concerns at other positions. Harmon can help the defensive front, but his recovery cannot retroactively supply a cornerback or another receiving option. Evaluating Khan's deadline decisions still requires looking at what the entire roster needs.

For Harmon, the immediate assignment is much simpler than that debate. Get through practice, build confidence in the injured foot and demonstrate that he can contribute when the staff calls his number. Pittsburgh will gain more from a sustainable return than a rushed appearance that produces another interruption.

A quiet deadline left fans searching for reasons to believe this team could improve. Harmon's practice window offers one worth following, with the next answer coming on the field. The Steelers now have a chance to turn a familiar face into meaningful help when their season demands it. That would be progress the entire defense could appreciate.
