Yes — according to the wiki, Terrion Arnold already signed with the Seahawks (as of the August 13 update), despite the ongoing legal case. (from the Terrion Arnold page)
A few things worth knowing:
- He's expected to compete for the No. 3 cornerback role behind Devon Witherspoon and Josh Jobe, with Riq Woolen's free-agent departure creating an opening.
- His availability is still uncertain — he may face placement on the NFL commissioner's exempt list, which would restrict his playing/practicing but let him attend meetings and collect pay.
- Mike Macdonald and the Seahawks are aware of the legal situation but willing to work through it. They have a built-in connection: DBs coach Karl Scott recruited Arnold to Alabama, and QB Jalen Milroe (a college teammate) vouched for him.
So the signing did happen — but his on-field status for 2026 remains up in the air pending the legal proceedings.
