The Seattle Seahawks are adding more size to the defensive line after the NFL draft.

Former Kansas State defensive tackle Uso Seumalo is signing with the Seahawks, NFL Network’s Tom Pelissero reported on April 25, citing Seumalo’s agents at NSA Football. The move gives Seattle another experienced interior defender after the team also used a seventh-round pick on Minnesota nose tackle Deven Eastern.

Seumalo is not a typical undrafted dart throw in terms of experience. Kansas State lists him with 50 career games over four seasons with the Wildcats after starting his college career at Garden City Community College.

That matters for a Seahawks team that has continued to value competition in the trenches. Seattle came out of draft weekend with a new rookie class, but the post-draft signing window is often where teams try to find developmental linemen who can push for a practice squad spot, steal a back-end roster role or give the staff a useful look during training camp.

Uso Seumalo Brings Seahawks a Big Interior Defender

Seumalo is listed by Kansas State at 6-foot-3 and 330 pounds, while USA Today’s player page lists him at 6-foot-3 and 340 pounds. Either way, the profile is clear: Seumalo is a big-bodied interior defensive lineman, not a tweener edge prospect.

His most productive season came in 2025, when Kansas State credited him with a career-high 20 tackles, 2.5 tackles for loss, 1 sack and 2 pass breakups in 12 games with 2 starts. He also had a career-high 6 tackles against Army and recorded a 14-yard sack against Texas Tech.

Seumalo’s earlier résumé gives the Seahawks a longer sample to evaluate. In 2023, he started 10 games, posted 18 tackles, 1.5 sacks, a pass breakup and a fumble recovery, and earned All-Big 12 honorable mention from the conference’s coaches. He played a reserve role in 2022 and 2024, giving Seattle tape of him both as a rotational piece and as a starter.

That versatility in role may be just as important as any single stat. Undrafted defensive tackles rarely arrive with a clean path to snaps, especially on a team that already spent draft capital on the position. Seumalo’s immediate job is more likely to be showing he can handle early-down work, absorb double-team attention and prove useful enough in camp to stay in the building.

Seahawks Double Up on Defensive Line Competition

Seattle’s decision to add Seumalo came after the Seahawks selected Eastern with the No. 242 pick. The team’s official draft tracker lists Eastern as a Minnesota nose tackle and a seventh-round selection.

That makes the Seumalo signing more interesting than a random post-draft addition. The Seahawks did not just take one swing at interior depth; they added at least two big defensive linemen in the same roster-building window.

That does not guarantee Seumalo has a direct route to the 53-man roster. It does suggest Seattle wanted more bodies competing at nose tackle and defensive tackle once the draft ended.

For fans, the question is not whether Seumalo should be projected as an immediate impact player. The more realistic question is whether he can turn a long college résumé and NFL size into staying power.

His background gives him a case. Kansas State credited Seumalo with 47 tackles and 5 sacks during his two-year junior college stint at Garden City before he became a multi-year contributor in the Big 12.

Draft Scout also listed Seumalo as a possible nose tackle and noted a potential offensive guard projection, a reminder that teams may view his frame and power as traits worth developing even if his NFL position is not fully settled.

Seumalo Gives Seattle Another Camp Battle to Watch

The Seahawks’ post-draft defensive line picture now includes another heavyweight option with real college experience.

Seumalo was not a high-sack college star, and his 2025 production should be framed accurately. His appeal is more about size, durability, interior depth and a chance to compete in a role where Seattle wanted more numbers after the draft.

That is enough to make the signing worth tracking.

The Seahawks have had success developing useful defensive line contributors from outside the early rounds, but Seumalo’s path will depend on the same things that define most undrafted linemen: conditioning, leverage, special-teams usefulness if applicable and whether he can show enough in preseason snaps to force a decision.

For now, Seattle has added a 50-game Kansas State defender to a post-draft class that already included another nose tackle. That gives the Seahawks more competition up front — and gives Seumalo his first NFL opportunity.
