Steelers Rookie Injured but Locked Into Final Roster: “I’m Betting All on Him!”

Pittsburgh, PA – August 26, 2025 – It was the kind of moment that made Steelers Nation hold its breath. Rookie defensive tackle Derrick Harmon, the team’s highly-touted first-round pick, was carted off the field in the preseason finale against the Carolina Panthers on August 22, a towel draped over his head, eyes red with emotion. For a few minutes, fear swept through the fanbase and even Mike Tomlin himself, but only days later the tunnel of doubt gave way to light. Pittsburgh is not letting go of its defensive gem – they are betting everything on him.

Midway through the second half at Bank of America Stadium, Harmon crumpled after colliding with Panthers tackle Brandon Walton. Clutching his knee in agony, he was wheeled away as many feared the worst: a lost rookie season. The update, however, brought relief. Diagnosed with an MCL sprain, Harmon is expected to miss four to six weeks. No surgery required, no season-ending blow. He is on track to begin the year on Injured Reserve with the right to return. “Derrick has a sprained knee and is being evaluated further,” Tomlin said after the game. “He’s exactly what we expected – a warrior.”

Harmon isn’t just another rookie. Drafted 21st overall out of Oregon, he was already penciled in as a cornerstone of the Steelers’ 3-4 front alongside Cam Heyward and Keeanu Benton. He had already flashed his promise with a sack against Tampa Bay in Week 2 of the preseason, after recording 45 tackles, 11 tackles for loss and 5 sacks in 2024 at Oregon, earning second-team All-Big Ten honors. Steelers legend Ben Roethlisberger put it simply: “He’s going to be a beast! I’m betting everything on Harmon – he’s going to explode once he learns from Heyward.”

On the sideline, it was Heyward who wrapped an arm around Harmon after the injury. “Injuries are part of the game,” Harmon recalled hearing. “Cam and T.J. Watt pulled me out of that low moment and kept my mind right.” By the fourth quarter, Harmon was walking the sideline on his own – a subtle but powerful sign of resilience that sideline reporter Missi Matthews captured: “Harmon walked back out there himself, a good sign.”

With the 53-man roster deadline arriving today, insiders across Pittsburgh agree Harmon is a roster lock. He will likely open the season on IR and could return as early as Week 4 in Dublin against the Vikings or Week 6 at home against the Browns. Defensive coordinator Teryl Austin reinforced the team’s faith: “Harmon is the future of this defense. Strength, speed, toughness – everything we need.” If Harmon misses time, veterans like Isaiahh Loudermilk or rookie Yahya Black may fill the gap, but no one doubts the impact once he returns. “He’s a wrecking machine,” Benton said. “This injury is just a pause – Derrick will be back to dominate.”

This setback is only one chapter in Harmon’s story. He recently lost his mother, Tiffany Saine, who passed away after multiple brain surgeries just weeks after watching him get drafted. “Her resilience is my greatest inspiration,” Harmon said. “She never quit, and neither will I.” That spirit is what the Steelers are betting on. When the season kicks off September 9 against the New York Jets, Steelers Nation won’t just see a rookie on the 53-man roster. They’ll see a promise – a future forged in steel, waiting to erupt.
