Dolphins' Zach Sieler Reportedly Played with Torn Biceps vs. Lions, Latest Rumors on Injury Status

Miami Dolphins defensive tackle Zach Sieler will miss the remainder of the 2026 NFL season with a torn biceps, according to ESPN's Adam Schefter.

Schefter reported the injury occurred on the first play of Miami's 19-9 loss to the Detroit Lions. Sieler proceeded to log 50 more snaps on defense and special teams.

The 31-year-old has been a stalwart along Miami's defensive front since first signing with the team midway through the 2019 season. He has appeared in 110 total games for the Dolphins.

As expected, this is a rebuilding year for Miami, which is tied for the NFL's second-worst record (1-7). Because of that, Sieler looked like a possible trade candidate prior to Tuesday's 4 p.m. ET deadline.

That option is obviously off the table now.

If the Dolphins believe they can make a quick turnaround in 2027, they may continue to see Sieler as an important piece of the defense. General manager Jon-Eric Sullivan might instead view his three-year $64 million extension a little differently due to the injury.

Designating Sieler as a post-June 1 cut next offseason would save Miami $13.2 million while putting $7.7 million in dead money on the cap in 2027 and then another $17.1 million in 2028.
