Injuries aren't just bad luck in the NFL; they're the silent architects of a team's season. One day you’re looking at a deep depth chart, and the next, your front office is scrambling to sign street free agents just to field a special teams unit.
The Pittsburgh Steelers are currently navigating that exact brand of chaos. In a move that signaled a shift in their defensive and back-end strategy, the Steelers place Thompson Harrison on IR, a decision that forced the coaching staff to look toward the practice squad for immediate relief.
It’s the kind of news that gets buried under headlines about quarterback controversies or trade rumors, but for the guys in the locker room, it changes everything.
The Reality Behind the Roster Shift
When news broke that the Steelers place Thompson Harrison on IR, the immediate reaction from fans was one of confusion. To be clear, we aren't talking about a single player named "Thompson Harrison." We are looking at a cluster of pivotal moves involving quarterback Skylar Thompson and linebacker Malik Harrison.
These two were essentially the "glue" players of their respective units. Losing them to the Reserve/Injured list at the same time felt like a gut punch.
Skylar Thompson’s situation is particularly frustrating. He was the guy who stayed late at the facility, the "emergency glass" the team hoped they’d never have to break. But a hamstring injury suffered during practice—one of those non-contact things that coaches absolutely hate—ended his immediate availability.

Then you have Malik Harrison.
He came over from the Ravens, a "thumper" linebacker who was supposed to solidify the run defense. He went down with a knee injury during the win against the Jets, and despite trying to gut it out, the medical staff ultimately made the call.
Why the Steelers Place Thompson Harrison on IR Now
Timing is everything.
Steelers management didn't just wake up and decide to clear space. They had to. Placing players on IR isn't just about acknowledging they are hurt; it’s about the 53-man roster math. By moving Thompson and Harrison to the shelf, the team opened up the oxygen they needed to sign Jabrill Peppers and elevate James Pierre.
Honestly, the Jabrill Peppers signing is the silver lining here.

Peppers brings a level of violence to the safety position that fits the Pittsburgh identity perfectly. If you're going to lose a depth linebacker and a backup QB, replacing them with a former first-round pick who can play "box safety" and return punts is a decent consolation prize.
Breaking Down the Depth Chart Casualties
- Quarterback Room: With Skylar Thompson on IR, the Steelers had to bring back Logan Woodside. It’s a revolving door. You've got Will Howard already dealing with a broken finger, so the QB room is looking more like a MASH unit than a football squad.
- Linebacker Rotation: Malik Harrison was the backup for both inside and outside roles. His absence puts massive pressure on rookie Payton Wilson and veteran Patrick Queen to stay healthy.
- Special Teams Impact: This is where the loss is felt most. Harrison and Thompson (if active) are the types of athletes who dominate on kick coverage.
What This Means for the Remainder of the Season
The NFL rules regarding the Reserve/Injured list have changed recently. Players placed on IR must miss a minimum of four games.
For the Steelers, this means they’ll be without these two through a critical stretch of the schedule. If you’re Mike Tomlin, you’re looking at the next month and wondering if your "next man up" philosophy can actually hold water this time.
The defense has been the backbone of this team. We’ve seen it time and again—the offense struggles, and the defense has to keep the score in the teens. When you start losing the guys who play the dirty snaps—the 15-20 snaps a game that don't show up on the highlight reel—the starters get tired. Tired players get hurt. It’s a vicious cycle.
The Jabrill Peppers Factor
Adding Peppers wasn't just a response to the IR moves; it was a response to the DeShon Elliott injury. Elliott’s MCL sprain left a crater in the secondary.

Peppers is a different kind of player. He's a hybrid. He can drop into the slot, he can blitz, and he can punish running backs in the hole. But he’s also learning a new playbook on the fly.
Misconceptions About the IR Moves
A lot of people think that once a player goes on IR, they’re "gone."
That's not the case anymore.
The Steelers have the option to designate players for return. Malik Harrison already showed he could return mid-season, having worked his way back from the knee issue to rejoin the 53-man roster later on. Skylar Thompson’s hamstring is more of a wait-and-see situation. Hamstrings are notorious for "lying" to players—you feel 100%, you sprint once, and it pops again.
Actionable Insights for Steelers Fans
If you're following the team's trajectory after the Steelers place Thompson Harrison on IR, here is what you should be watching:
- Watch the Practice Squad Elevations: Keep an eye on guys like D'Shawn Jamison and Tre Flowers. These are the players who will be filling the gaps left by the veterans on IR.
- Monitor Snap Counts: See how many extra snaps Payton Wilson is taking. If his snap count jumps from 30% to 70%, the team is at risk of "rookie wall" burnout.
- The Quarterback Carousel: If Howard isn't ready and anything happens to the starter, Logan Woodside becomes the most important person in Pittsburgh. That should tell you everything you need to know about the current state of the roster.
The Steelers are essentially playing a high-stakes game of Tetris with their roster. Every time a piece like Thompson or Harrison falls out, they have to rotate a new one in perfectly, or the whole thing starts to stack up against them. For now, they've stabilized the ship, but the margin for error has never been thinner.
Next Steps for the Roster
The front office will likely continue scouting the waiver wire for interior linebacker depth. While the Peppers signing helps the secondary, the "thumper" role vacated by Harrison remains a concern for heavy-personnel matchups. Expect a few more "Reserve/Future" contract signings as the team looks toward the 2026 offseason to fully repair the damage done by this injury-plagued stretch.
