The Seahawks signed rookie defensive tackle Thor Griffith on Tuesday. Griffith, an undrafted rookie out of Louisville, took part in Seattle's rookie minicamp as a tryout player.
Nose tackle Justin Rogers, who signed with Seattle last week, was waived to make room on the 53-man roster.
Griffith, who is 6-foot-2, 305 pounds, began his college career at Harvard where he was an All-Ivy League first-team selection as well as an AFCA and FCS Football Central second-team All-America pick after recording 55 tackles, 11 tackles for loss and 3.5 sacks in 2023. In his three-year career at Harvard, Griffith recorded 132 tackles, 33.5 tackles for loss and 13.5 sacks in 30 games.
Griffith then transferred to Louisville last year, appearing in 13 games with 21 tackles, 3.0 sacks, six tackles for loss and a forced fumble.
