Cook, 25, has skipped the team’s voluntary offseason program, including workouts in April and OTAs on May 27–29, June 2, and June 5. He was the only Bills player absent in May, as 89 of 90 players were in attendance. The team’s mandatory minicamp, scheduled for June 10–12, looms as another key moment in the negotiation timeline.

The Buffalo Bills are heading into an important 2025 NFL season. After being so close to the Super Bowl in recent years, the window of contention is still open. Last season, the Bills came up just short in the AFC Championship Game against the Kansas City Chiefs.
