The Buffalo Bills have officially fortified their defensive lineup by signing veteran outside linebacker Mike Danna to a one-year deal. This transition follows Danna's six-year tenure with the Kansas City Chiefs, where he established himself as a consistent defensive contributor after being drafted in 2020. To accommodate his arrival on the active roster, the organization subsequently announced the departure of cornerback MJ Devonshire. Beyond this specific transaction, the report highlights a broader series of offseason personnel moves, including the acquisition of various free agents and the signing of recent draft picks. These strategic additions reflect the team's ongoing efforts to build roster depth and experience across multiple positions for the 2026 season. Danna is expected to bring significant field experience to the linebacker unit, having appeared in nearly ninety professional games.
