Overview

• Seattle released defensive tackle Thor Griffith two days after signing him to free up a roster spot during training camp.
• The team signed undrafted cornerback Keydrain Calligan, who was cut by the Houston Texans last week.
• Calligan ran a 4.42-second 40-yard dash at his pro day and posted an 8.78 Relative Athletic Score, underscoring his explosiveness.
• Griffith, a 6-foot-2, 305-pound prospect from Harvard and Louisville, went undrafted in 2024 and recorded 19 tackles with three sacks in his final college season.
• These rapid transactions reflect Seattle’s ongoing evaluation of undrafted talent as it refines positional depth ahead of its August 7 preseason opener.
