Dolphins, DT Zach Sieler agree on a $67.75 million contract extension

By Canadian Press on August 3, 2025.

MIAMI GARDENS, Fla. (AP) — Defensive lineman Zach Sieler and the Miami Dolphins on Sunday agreed on a three-year contract extension worth up to $67.75 million, including $44 million guaranteed.

Agent Drew Rosenhaus confirmed the deal, which was first reported by ESPN.

Sieler, a leader of Miami’s defense, seemed likely to get a raise after consecutive 10-sack seasons with two interceptions — one returned for a touchdown in 2023 — 118 total tackles, 24 tackles for loss and two forced fumbles.

A seventh-round pick by Baltimore in 2018, Sieler was waived by the Ravens in his second season and claimed off waivers by the Dolphins in 2019. During his six years in Miami, Sieler has become one of the league’s most productive defensive tackles with 30 sacks in 65 starts.

Sieler, who turns 30 in September, had two years left on a deal that he signed in 2023, which paid him $10.25 million annually. He’s now signed through the 2029 season.
