Zach Sieler: Everything you need to know

Sieler made 47 tackles (29 solo), including 5.5 sacks, across 17 regular-season games in 2025. He also had one pass defensed and one fumble recovery. Sieler played two more games in 2025 than he did in 2024, but he nonetheless finished with just more than half the 10.0 sack total he had managed in each of Miami's prior seasons. The 30-year-old defensive tackle is under contract with the Dolphins through 2029, but the team will have a potential "out" in his contract after the 2026 campaign, making it potentially crucial for Sieler to bounce back to his usual production level next season.

Sieler registered four tackles (three solo), including 2.5 sacks, in Sunday's 34-10 Week 14 win over the Jets. Coming into Sunday, Sieler had just 1.0 sacks through 12 games. He didn't record any defensive stats in the first half against New York but then detonated for 2.5 sacks across the final two quarters. Sieler probably isn't going to reach double-digit sacks for a third straight season -- he's at just 3.5 through 13 games -- but for one game at least, he was a forceful part of the Dolphins' pass rush.

Sieler tallied three tackles (three solo) during Miami's loss to the Colts on Sunday. Sieler ended up having a solid performance in what was overall a poor showing for the team. The 30-year-old has racked up 10.0 sacks in each of the last two campaigns, and will look to record his first of the season during Miami's Week 2 matchup versus the Patriots.
