Former Tennessee Volunteers defensive lineman Matthew Butler was released by the Miami Dolphins on August 3, 2026, as the team trimmed its roster ahead of the upcoming NFL season.
A Growing Wave of Volunteer Exits
Butler’s departure is the third cut involving recent Volunteers, following the waiver of wide receiver Joey Aguilar by the Jacksonville Jaguars and the release of defensive back McCallen Castles by the Green Bay Packers.
Although Butler had logged half a sack during preseason action and was slated to serve as a rotational third‑string tackle, the Dolphins concluded that he did not align with their defensive scheme and opted not to retain him for the 2026 campaign.
The moves reflect a broader pattern of Tennessee alumni facing roster challenges as teams finalize their 53‑man squads, a trend that could influence how the program’s prospects are evaluated heading into free agency.
