The Dolphins’ offense is set to receive a major boost in Week 8. The team’s defense will, on the other hand, be missing a key contributor for the time being. 
Defensive tackle Zach Sieler suffered an orbital bone fracture in practice, Cameron Wolfe and Ian Rapoport of NFL Network report. He will be out for Week 8 at a minimum, but further evaluation will be needed to determine a firm recovery timeline. It remains to be seen if surgery and/or a stint on injured reserve will be required.
Missing Sieler for an extended period would deal a blow to Miami’s defensive front. The former seventh-rounder has emerged as a full-time starter during his time with the Dolphins, which dates back to the 2019 campaign. Sieler has logged a snap share of at least 77% each season since 2022, serving as a key member of the team’s D-line. Especially with free agent departure Christian Wilkins no longer in the picture, Sieler’s presence is crucial on a defense which ranks fourth in yards allowed per game.
The 29-year-old has been an important run-stopping presence over the past several years, and he chipped in as a secondary pass-rushing option as well before landing an extension last summer. That three-year, $30.75MM pact raised expectations, and Sieler delivered in 2023 with a career-high 10 sacks. Now that Wilkins is gone, Sieler has been counted on to a larger extent in terms of providing an interior rush presence. Being without it for a lengthy stretch would hinder a defense which already ranks 30th in the NFL in sacks.
Moving Sieler to IR would ensure at least a four-game absence. When speaking about the injury on Friday, head coach Mike McDaniel deemed the situation week to week (h/t Barry Jackson of the Miami Herald), so the outcome of further testing will be crucial in determining how long Sieler is sidelined for. The likes of Calais Campbell, Benito Jones and Brandon Pili will be counted on to handle a larger workload along the D-line in his absence.
