Bills’ early-season depth test: Zane Durant, Phidarian Mathis, Dorian Strong and Tyrell Shavers start on injury lists

The Buffalo Bills are heading into the opening stretch of the season with several players unavailable due to injury and related designations, an outcome that commonly follows NFL roster cutdown day procedures. According to Yahoo Sports, the team placed rookie Zane Durant on injured reserve with a designation to return, while Phidarian Mathis was listed on the suspension list. Two additional players, Dorian Strong and Tyrell Shavers, were also placed on the non-football injury list and the physically unable to perform list, respectively.

Each designation carries different implications for when a player can return and how the Bills can plan the early weeks. An injured reserve designation with a path to return means the player is not immediately available, but the team retains a controlled opportunity to activate him later if he meets league and team requirements. A suspension list placement, by contrast, ties availability to the nature of the situation and the league’s process, meaning a timetable is less about week-to-week medical progress and more about the underlying status.

The non-football injury list generally indicates a player is dealing with an issue that did not originate from team activities, which can affect both the timeline and the way the team manages practice and rehabilitation. The physically unable to perform designation is often used when a player cannot participate at the start of training camp or the season due to physical limitations, again pushing the decision forward rather than treating it as a simple day-to-day absence.

For Buffalo, the practical impact is the same even if the labels differ. The Bills will need to fill reps in the short term and develop contingency plans for defensive depth and depth roles that frequently get exposed when the game-week rotation is compressed by early absences. With multiple players carrying different availability categories, the team’s internal depth chart could see more movement than a typical single-injury scenario.

The list also underscores how NFL roster management works at the margins. Teams do not simply wait for the regular season to begin when they know certain players are not ready. Instead, they use designated lists to align roster status with availability, while preserving the ability to make later changes that match the rules for return, activation, or resolution.

What to watch next is how Buffalo structures practice reps and game-week roles for the players stepping into the gaps. If Durant’s designation to return becomes viable, the Bills’ coaching staff will likely be monitoring workload and readiness closely once his eligibility window opens. Meanwhile, the suspension list status for Mathis and the PUP and NFI timelines for Strong and Shavers will determine how quickly, or slowly, the Bills’ depth stabilizes over the first stretch of the schedule.

Because this is based on a report rather than an official league release in this account, specific dates and any later updates are not addressed here. Even so, the mere presence of four separate designations gives a clear message about the early-season challenge: Buffalo’s rotation will be built around what is available now, then adjusted when each designation’s path to activation or resolution becomes clear.
