What happened: Lions coach Dan Campbell addressed the Seahawks' agreement to sign Terrion Arnold, saying he wasn't surprised other teams did their research on the cornerback. Campbell said he has no ill will toward Arnold and wished him well. The signing remains unofficial as Seattle works out details with the league.

Why it matters: Detroit selected Arnold 24th overall in the 2024 draft but cut him in June following his arrest, choosing not to add a direct roster replacement. D.J. Reed and Rock Ya-Sin have taken over as starters in training camp, with Nick Whiteside working as a backup.

What to watch: Watch for the Seahawks and the league to finalize the terms and timing of Arnold's signing.
