The Buffalo Bills began Day 1 of their mandatory minicamp on June 9 with a mixed injury report typical of June: one key defensive player returning to the field while two others watched from the sidelines.
Defensive end Michael Hoecht practiced for the first time since suffering a torn Achilles late in the 2025 season. Meanwhile, linebacker Dorian Williams and safety Cole Bishop were absent from practice.
This split tells a critical story about the Bills' defensive depth chart battles as they head into the 2026 training camp.
Michael Hoecht's return is a significant boost.
The 28-year-old defensive end signed a three-year, $21 million contract last offseason and appeared in 15 games in 2025 before his Achilles injury prematurely ended the year. According to Over the Cap, the Bills currently carry roughly $9.81 million in cap space with $46.21 million in dead money commitments, making value signings like Hoecht's crucial.
Hoecht is not a superstar by traditional metrics; he has yet to reach double-digit sacks in any season. However, he is a high-motor, versatile lineman that defensive coordinator Jim Leonhard values highly for his scheme, which requires ends to be effective in both pass rush and run defense. In 2025, Hoecht recorded 45 tackles, 4 sacks, and 9 quarterback hits. Those stats modestly reflect a solid starter on a defense that finished 11th in DVOA last year.
Getting Hoecht back on the field during minicamp--even in a limited role--means the Bills have a good chance of having him ready for training camp in July. His presence also allows rookie Landon Jackson, the 2025 fourth-round pick who played 291 snaps as a rookie, to remain a situational pass-rush weapon rather than being pressed into a starter's workload.
The absence of linebacker Dorian Williams is a more concerning development.
Williams enters his fourth NFL season with the Bills after being selected in the third round of the 2023 draft. He has been groomed as a key piece alongside Terrel Bernard in the linebacker corps. The 2025 campaign saw Williams starting 13 games and logging 87 tackles, 2 sacks, and 5 tackles for loss across 712 defensive snaps. While not elite, he proved to be an adequate contributor on a team mindful of cap constraints.
General manager Brandon Beane commented on June 5 that the team seeks "more youth" and aims for "an infusion of some youth" across the roster. Williams fits this profile as a 25-year-old under contract through 2027 at a modest salary of under $1.5 million this season.
Though the Bills have not publicly detailed the reason for Williams' absence from minicamp, missing reps in a defense that relies heavily on linebacker communication and disciplined run fits is a setback. With new veterans like Bradley Chubb and Greg Rousseau playing specialized off-ball roles, every practice rep counts for Williams to build chemistry and understanding within the revamped linebacker room.
Safety Cole Bishop's absence is equally noteworthy.
Bishop, a 2024 second-round pick, was heralded as the safety of the future behind established starters at the position. He saw limited action as a rookie with only 186 defensive snaps, backing up Taylor Rapp and Damar Hamlin. After letting Rapp depart in free agency, the Bills planned for Bishop to start alongside Hamlin in 2026. However, the signing of Geno Stone in free agency and selection of Jalon Kilgore in the fifth round added competition.
Bishop's missed practice time opens opportunities for Stone and Kilgore to gain valuable repetitions with the first-team defense. Stone is a proven NFL starter with 12 career interceptions and a strong passer rating when targeted in 2024. Given his experience and a reported $6 million-per-year contract, the Bills are unlikely to simply hand the starting job back to Bishop without a fight.
It is reasonable to predict that Bishop will not be the starting safety on opening day, with Stone likely to earn that role. Bishop's missed developmental time, combined with competition and financial investment in Stone, weighs against an easy path to a Week 1 starter role.
Implications for the Bills' defensive depth chart.
Buffalo's 2026 defense hinges on multiple players returning from injury or showing growth. It remains a delicate foundation that could unravel without adequate health and development.
On the defensive line, Hoecht's recovery is a positive sign. Alongside Ed Oliver, Greg Rousseau, and Mike Danna, the Bills boast a promising front four. The biggest question mark is 2025 second-round pick Deone Walker, who showed pass-rush potential in 348 snaps but needs work defending the run. A healthy Hoecht will help stabilize the line and provide rotational depth.
At linebacker, Williams' missed reps are worrisome. Terrel Bernard serves as the green-dot communicator, but the second inside linebacker spot lacks certainty. Fourth-round rookie Kaleb Elarms-Orr has the physical tools to compete, but relying on a rookie to grasp Jim Leonhard's detailed linebacker responsibilities is risky. Bradley Chubb remains a specialist, not a three-down linebacker. Extended absence by Williams could force Buffalo to seek veteran help before the season starts.
At safety, Bishop's absence represents a lost chance to progress during a critical offseason period. He must develop timing, coverage communication with Hamlin, and coordination with Stone. Each practice he misses is an opportunity gained by Stone or Kilgore, reaffirming that youth needs reps to materialize into NFL starters.
The bigger picture for Buffalo.
The Bills enter 2026 with a core led by franchise quarterback Josh Allen, who in 2025 threw 25 touchdowns and added 14 rushing touchdowns. James Cook followed with a breakout 1,621-yard rushing season. The roster on paper is built to contend for the AFC East.
However, the team's $46.21 million dead money figure -- the fourth-highest in the NFL -- severely limits roster flexibility and depth. This means that every injury to a key rotational player inflicts disproportionate damage.
Hoecht's ability to return healthy and productive is a crucial win. Meanwhile, Williams' and Bishop's absences from minicamp are early warning signs that could ripple into the summer and training camp. The Bills can ill afford to have promising young defenders behind schedule.
General manager Brandon Beane invested heavily in youth during the offseason and is betting on health and development to push the Bills close to championship contention. The first day of minicamp provides a snapshot: one hopeful sign with Hoecht's comeback and two cautionary flags with Williams and Bishop sidelined.
In sum, Hoecht's return stands out as the most important development for the defensive unit. Conversely, an extended absence by Williams has the potential to create instability in the linebacker corps that Buffalo cannot afford. The margin for error is slim; the Bills must have these young players fully ready when training camp opens in about five weeks.
The clock is ticking on Buffalo's roster construction, and June's mandatory minicamp offered both encouraging news and concerns for a defense that must perform under tight financial and roster constraints in 2026.
