Zach Sieler Out for Season Following Biceps Tear vs. Lions

Miami Dolphins veteran defensive tackle Zach Sieler will miss the remainder of the 2026 season after sustaining a biceps tear during Sunday's game against the Detroit Lions. Sieler's season-ending injury prompted the Dolphins to make a roster move on Wednesday, signing defensive tackle Keith Cooper Jr. off the Carolina Panthers' practice squad to fill the vacant spot on the active 53-man roster.
