The defensive captain ruptured his biceps on the opening play against the Lions but played through the rest of the game before the injury was confirmed as season ending.
Zach Sieler will undergo season-ending surgery for a ruptured biceps, the Dolphins' latest blow to a defense that can't seem to catch a break. The injury happened on the opening play against the Lions, which is about as early as it gets, yet Sieler stayed on the field and finished out the game anyway.
That kind of toughness is part of why he wears the captain's patch, but it doesn't change the outcome. Miami now has to replace one of its top defensive linemen for the remainder of the season, a significant loss up front for a unit that relies on him to anchor the interior.
No further details on the surgery timeline or Sieler's recovery have been reported. The Dolphins will need to adjust their defensive line rotation to cover the absence as the season continues.
