The Seahawks signed Igbinoghene to a one-year contract Saturday, Michael-Shawn Dugar of The Athletic reports.
Igbinoghene is a six-year NFL veteran who has spent time with Miami, Dallas and Washington. Last season with the Commanders, he played in 15 regular-season games (two starts), registering 35 tackles (including 1.0 sacks) and five defensed passes. Igbinoghene also logged some work as a kick returner, taking seven kickoffs for 191 yards (27.3 YPR). He'll likely work in a rotational role at cornerback and serve as a depth option in the return game with Seattle.
