Miami Dolphins defensive lineman Zach Sieler may not be present when training camp opens, as tensions grow between the player and the organization over contract negotiations. According to multiple sources close to the situation, Sieler is considering a holdout as he seeks a new deal that better reflects his performance and value to the team’s defense.
Sieler, who signed a three-year extension with the Dolphins in 2023, has reportedly outperformed the terms of that contract and now seeks a raise that would put him in line with other top interior defensive linemen around the league. The 28-year-old had a career year in 2024, recording 8.5 sacks, 14 tackles for loss, and 19 quarterback hits while serving as one of the anchors of Miami’s front seven. His production, leadership, and durability have made him a cornerstone of the team’s defense.
Despite his strong play, Sieler’s current deal is relatively modest compared to other players at his position. The lack of guaranteed money beyond this season is another sticking point, as the veteran defender is seeking greater long-term security. Negotiations between his representatives and the Dolphins front office have been ongoing, but no significant progress has been reported as of early July.
A potential holdout would be a major storyline heading into training camp. While Sieler has not publicly confirmed his intentions, his absence from voluntary OTAs earlier this offseason has fueled speculation. If he does opt to hold out, it could affect team chemistry and preparation as the Dolphins aim to contend for the AFC East title and make a deep playoff run in 2025.
Head coach Mike McDaniel and general manager Chris Grier have both expressed their appreciation for Sieler in the past, with McDaniel calling him “a quiet leader who sets the tone every day.” However, it remains to be seen whether the organization is willing to make the financial commitment necessary to keep Sieler happy and in uniform.
If the situation remains unresolved, the Dolphins may be forced to make a difficult decision: renegotiate Sieler’s contract to retain a key defensive presence or risk weakening their defensive line at a critical juncture in the season. Fans and teammates alike will be watching closely to see how this contract standoff unfolds in the coming weeks.
