Pittsburgh Steelers Cut Juan Thornhill Amid Defensive Struggles
The Pittsburgh Steelers announced on Wednesday, November 12, 2025, that they have waived veteran safety Juan Thornhill. This decision follows a series of subpar performances and comes as the team faces significant challenges in its secondary.
Thornhill’s Departure Signals Defense Shift
Originally expected to replace Minkah Fitzpatrick this season, Thornhill started Week 2’s loss to the Seahawks and played every defensive snap. However, his performance in a subsequent game against the Packers was so poor that he was benched. Since then, he has not played a defensive snap in two consecutive games.
Thornhill’s exit is part of broader changes in the Steelers’ defense.
The team is now claiming Sebastian Castro off waivers from Tampa Bay. Castro initially signed with the Steelers as an undrafted free agent out of Iowa but did not make the initial roster. He was later signed to the practice squad and used sparingly.
Steelers’ Defensive Challenges Persist
The Steelers’ defensive struggles extend beyond Thornhill’s departure. Cornerback Brandin Echols, who had shown promise at the start of the season, performed poorly against the Chargers due to injuries and roster management issues. Echols played 64% of the defensive snaps plus 11 special teams snaps, highlighting the team’s reliance on him.
Other players like Mark Robinson and Chuck Clark also saw limited playing time, with Robinson only appearing in one snap on special teams after being elevated from the practice squad.
The Steelers are exploring ways to better manage their roster to alleviate the defensive pressure, including making more use of receiver Roman Wilson as a gunner.
Coach Mike Tomlin acknowledged the challenges faced by his team: “That’s just football. When you’ve got a limited number of people available to you, this isn’t college football. We don’t have a hundred guys on the sideline, and so certainly when attrition happens, man, you get challenged collectively.”
Future Implications for Steelers Defense
The move to waive Thornhill and bring in Castro signals potential long-term changes in defensive roles. Jalen Ramsey’s position as free safety is now more firmly established, with the possibility of Jabrill Peppers returning from injury to compete for that role.
While the Steelers continue to shuffle their roster in hopes of stabilizing their defense, the performance issues remain a concern heading into crucial games. The team will need to find solutions quickly if they hope to avoid further collapses and maintain competitive form across the season.
