Seahawks elevate veteran CB Trevon Diggs from practice squad ahead of 49ers visit

The Seahawks made a defensive backfield move ahead of Sunday’s game against the 49ers, signing cornerback Trevon Diggs from the team’s practice squad. The transaction elevates Diggs onto the Seahawks’ active roster, giving Seattle an additional experienced option in the secondary for a division opponent it will face in a key weekly test.

For Seattle, the timing of the signing matters because a game against San Francisco typically demands more than one look at the way the 49ers move receivers around and attack vertically. Adding Diggs gives the Seahawks another corner capable of matching up in coverage packages and rotating through sub packages, particularly when the defense needs to manage third-down passing situations.

Diggs’ role with Seattle begins immediately, as the Seahawks’ announcement framed the signing as preparation for Sunday’s contest. Moving from a practice-squad assignment to a game-week roster spot usually indicates that coaching staff believes the player can contribute on game day, whether as a coverage specialist, a depth piece, or a situational starter depending on how Seattle structures its secondary rotations.

Seattle’s decision also reflects a broader NFL reality, where practice squads function as a flexible talent pool. Elevations like this are often used to close skill gaps revealed in the first part of a season, adjust for how opponents attack, or respond to the day-to-day needs of the active roster as matchups change from week to week.

From San Francisco’s perspective, the Seahawks’ addition changes the look Seattle can present in the back end. While specific coverage assignments are not disclosed in the team announcement, signing a veteran corner ahead of a marquee opponent typically affects game planning, since it can influence matchups, personnel groupings, and how much help the defense is able to provide over the top.

The next step is straightforward for both teams: how Diggs is used once the game gets underway, and whether Seattle’s secondary can limit the big plays that often define outcomes in matchups between these clubs. With the signing confirmed by the Seahawks, the focus now shifts to Sunday’s play on the field.
