Seahawks keep training-camp roster churning, adding a former UDFA linebacker while another linebacker is waived and/or listed as injured

The Seattle Seahawks are continuing their training-camp roster churn, adding a former undrafted free agent linebacker while another linebacker has been waived and/or placed on the injured list, according to a report from Yahoo Sports on Aug. 1, 2026. For teams trying to defend a championship, these moves are rarely headline-grabbing, but they are often decisive for who earns the last guaranteed spots and who gets the reps that carry into the regular season.

The Seahawks enter this stretch as the defending Super Bowl champions, after defeating the New England Patriots 29-13 in Super Bowl LX earlier this year. With championship teams, the foundation is usually set, but the depth and the special-teams-ready players are the variables. Training camp is where Seattle compresses a long evaluation cycle into a few weeks, testing physical readiness, football instincts, and the ability to contribute on short notice.

Linebacker is a position where small differences show up quickly. Coaches look for how quickly a player reads formations, whether he can carry assignments in coverage, and how reliably he fits run-defense gaps. On rosters, the linebackers on the margins are also often tasked with special teams roles, meaning coaches may prioritize tackling technique, discipline in pursuit, and communication over pure athletic ceiling.

The reported sign-and-waive sequence also underscores the reality of modern NFL camp: availability changes constantly. Even when a team believes a player is on track, a separate injury designation or an eligibility decision can force immediate roster adjustments. That is why teams commonly bring in former UDFA players, who are frequently developed through a repeatable process: install fundamentals, prove effort, and then earn specific responsibilities through camp performance.

From the Seahawks’ perspective, the immediate football question is simple: which linebacker can help Seattle’s depth chart absorb the next bump in the road? Training camp reps tend to sort players into a few categories, such as those who can start alongside established pieces if called on, those who can contribute primarily on special teams, and those who will likely need more time. A new addition from the UDFA pipeline is typically aimed at closing a gap in one of those categories.

It is also important to note what this kind of transaction does not automatically determine. A signing does not guarantee a long-term roster role, and a waiver or injury designation does not necessarily reveal how severe the setback is. In August, many outcomes still hinge on subsequent practice evaluations, day-to-day availability, and how the rest of the group responds to coaching emphasis.

What to watch next for Seattle is the pattern of linebacker utilization over the remainder of camp. If the newly signed former UDFA linebacker is used early in scout-team and special-teams work, that can indicate the team’s interest in converting practice speed into game-day usefulness. Separately, monitoring how the Seahawks adjust their depth chart if the waived/injured player’s availability changes can reveal how much the organization expects to rely on veteran depth versus continued churn at the margins.

Ultimately, Seattle’s championship identity will be defined by the core starters, but in the NFL, championships are also defended by who is ready when the roster changes. These August moves are an early chapter in that work, and they can influence the final training-camp roster decisions that decide who makes the team when the calendar flips to the regular season.
