Seahawks Add Fullback Brock Lampe, Waiving Tight End Lance Mason for Roster Spot

The Seattle Seahawks signed fullback Brock Lampe, the team announced Thursday, a move that also triggered another personnel change on the 90-man roster. To create room for Lampe, the Seahawks waived tight end Lance Mason.

In the NFL, the 90-man roster is a gatekeeper during the offseason and early stages of roster building. Teams use the limit to balance depth across positions while they evaluate players in practice and preseason preparation. Moves like these often reflect a team’s immediate priorities for run-game personnel, special teams coverages, and practice-week matchups.

Lampe’s addition gives Seattle another option at fullback, a position that can matter beyond the stat sheet. Fullbacks are typically used as run-game blockers, lead blockers in short-yardage situations, and versatile pieces in protection and movement packages. Even when their carries are limited, fullback personnel can shape how an offense distributes defenders at the line of scrimmage.

The Seahawks’ decision to waive Mason to make space underscores the roster squeeze that teams face when they adjust personnel week to week. Tight ends can overlap with several roles, including pass-catching targets, additional blockers, and special teams contributors, but the timing of roster moves means one unit’s depth can affect another.

Beyond the transaction itself, the practical impact is how Seattle’s coaching staff will organize reps. With Lampe now in the mix, he can be evaluated alongside existing fullback or hybrid blocking options. Meanwhile, Mason’s waiver places him into the waiver process, where other teams may claim him if they see a fit for their depth needs.

For fans tracking the Seahawks’ formation for the season, this move is a reminder that roster construction is not only about the starters. Depth pieces at fullback and tight end can influence who gets meaningful snaps in the run game and who provides reliable coverage on special teams. The Seahawks’ early roster choices also hint at how they expect to balance personnel groupings as training camp progresses.

The next thing to watch is whether Seattle fills any additional gaps after the waiver and how Lampe fits into the team’s practice usage. Because this is a roster transaction related to the 90-man limit, it may be followed by further adjustments as other players return from offseason procedures and as the team narrows its group heading toward the next roster cut.
