Dolphins Zach Sieler Sends Strong Message to Team Amid Season-Ending Injury

The Miami Dolphins were hit with a heartbreaking injury, as team leader and captain Zach Sieler suffered a season-ending injury during the team's Week 9 loss to the Detroit Lions.

Sieler suffered a ruptured biceps but continued to play through the game, head coach Jeff Hafley revealed. Now, the Dolphins lineman sent a strong message to the team following the injury.

Sieler has been one of the most important players on the Dolphins since his arrival in 2019. His work ethic and passion led to a quick ascension on the defensive side of the ball, but in total, with the leadership on the team. 

The defensive tackle's play led to a three-year, $64 million contract extension. Despite rumors that Sieler would end up being traded, that was never corroborated or happened.

New general manager Jon-Eric Sullivan and head coach Jeff Hafley spoke about Sieler in the same manner they did with the other "three pillars" of the team, which include running back De'Von Achane, center Aaron Brewer, and linebacker Jordyn Brooks.

All three received their own extensions in the 2026 offseason.

Sieler was having a very strong year, securing two sacks thus far through eight games. However, he is now out for the season.

The Dolphins captain posted a strong message to the team on Instagram, stating he plans to be around helping, despite suffering a significant injury. 

"Not the way I thought my season would end, but it’s not the first time that I have been faced with adversity. The work never stops, and I won’t either. I look forward to continuing to be around my teammates and helping out in any way I can," Sieler said. 

One way that Sieler can help the Dolphins is by continuing to guide the young defensive players, especially those on the line.

With Sieler being out for the season, it will presumably be Zeek Biggers who will step into the starting role. Jordan Phillips has been a starter and has made his own waves, and now Biggers will get a bigger role.

Kenneth Grant is also a backup, and the Dolphins brought back Keith Cooper Jr. to act as depth and rotation. 

Losing Sieler will be tough for the Miami defense, as he was one of the strongest and most dependable. It will especially have an impact on the pass rush, which was starting to find footing.

The Dolphins have picked up eight sacks over the last three games, after the defensive unit posted none for multiple weeks. Without Sieler, the team may struggle to generate pressure on opposing quarterbacks.

This is where Biggers will need to step up and prove that he is the future of the Miami defensive line. 

The Dolphins will have their chance to test life without Sieler on Sunday, as they face the struggling Indianapolis Colts.
