Seattle signed Lampe on Thursday, John Boyle of the Seahawks' official site reports.
Lampe spent the 2025 season on New England's injured-reserve list after going undrafted out of Northern Illinois, and now he'll compete for a roster spot on the team that beat the Patriots in the Super Bowl. At a minimum, he should be able to handle some of the practice reps vacated by 2025 fifth-rounder Robbie Ouzts as he tends to an undisclosed injury.
