Blair posted nine tackles (nine solo) in Thursday's 27-11 preseason loss to the Bears.
Blair underwent knee surgery in October of last year and missed the rest of the 2021 season. He's since been cleared and is a full-go, and he led the Seahawks in tackles Thursday. The 2019 second-round pick has struggled to stay healthy in his career, but he has a good chance to make the 53-man roster after the Seahawks traded DB Ugo Amadi to the Eagles last week.
