The Seattle Seahawks might be in a holding pattern with their signing of cornerback Terrion Arnold, but the team isn’t standing pat in examining potential upgrades to its secondary.

Two-time Pro Bowl cornerback Trevon Diggs is signing a one-year contract with the team on Wednesday, Aug. 19, according to multiple reports.

Diggs worked out for the Seahawks on Tuesday, Aug. 18.

Seattle’s staff has plenty of familiarity with the former Dallas Cowboys standout. Defensive coordinator Aden Durde was the Cowboys’ defensive line coach from 2021-23, a span in which the cornerback established himself as one of the NFL’s premier ballhawks. Defensive backs coach and defensive passing game coordinator Karl Scott was also Diggs’ position coach at Alabama for the final two years of the former Crimson Tide standout’s collegiate career.

Latest on Seahawks, Terrion Arnold

Despite Arnold having yet to sign his contract with the Seahawks, ESPN’s Adam Schefter reported that the team still plans to move forward in adding the former Detroit Lions first-round pick.

Arnold, who faces eight felony charges for allegedly coordinating and directing the kidnapping and robbery of three men in Tampa, Fla., is expected to be placed on the commissioner’s exempt list once signed by a team. Upon receiving that designation, he would be ineligible to play in games or participate in practices, though he would be permitted to attend meetings.

In the third episode of this season’s “Hard Knocks,” Seahawks general manager John Schneider acknowledged that he likely would have released Arnold had the cornerback been on Seattle’s roster at the time of his arrest.

“Because it’s just the nature of, like, when you’re the team, it’s different than the second-chance team,” Schneider said in a conversation with special teams coordinator Jay Harbaugh.

The Lions released Arnold on June 29, five days after he voluntarily surrendered himself to authorities.

Diggs’ latest chance

Diggs, 27, is looking to stick with a team after he was waived by the Cowboys last December.

He was subsequently claimed by the Green Bay Packers and joined the team for the regular-season finale and the wild-card playoff loss to the Chicago Bears. But that two-game stint proved to be little more than a trial run, with the team releasing him later in January rather than paying out his non-guaranteed $14.5 million salary in 2026.

In Seattle, he joins a secondary in search of additional help after Riq Woolen’s departure. The Seahawks re-signed Josh Jobe this offseason to solidify the spot opposite three-time Pro Bowler Devon Witherspoon, who on Aug. 15 agreed to an extension that makes him the league’s highest-paid cornerback. But the team has scant depth behind the two of them.
