What happened: The Bills secured defensive tackle Greg Gaines in a mid-August free agency addition. To accommodate the signing, the organization released Tommy Akingbesote from the preseason roster.

Why it matters: The adjustment injects experienced depth into the interior trench rotation. The coaching staff will use the remaining exhibition schedule to evaluate how the new acquisition fits the defensive scheme.

What to watch: Gaines is expected to begin taking practice reps immediately as positional battles intensify.
