Dolphins DT Zach Sieler Undergoing Season-Ending Biceps Surgery

Schefter adds Sieler is expected to have a five- to six-month recovery after getting injured on the first play in Week 9 and finishing the game.

Sieler, 31, is a former seventh-round pick of the Ravens back in 2018. He signed a four-year, $2.5 million contract and managed to make the 53-man roster as a rookie.

However, the Ravens elected to waive Sieler coming out of the preseason in his second year. He had a brief stint on their practice squad before being claimed off of waivers by the Dolphins. 

Miami brought Sieler back on an exclusive rights contract in 2020 and later that year signed him to a three-year, $7.6 million extension. The Dolphins re-signed him to a three-year extension with a maximum value of $38.65 million in 2023.

They re-signed him to another three-year extension worth $67.75 million during camp in 2025.

In 2026, Sieler appeared in eight games for the Dolphins and recorded 24 total tackles including seven tackles for loss and two sacks.
