The Seahawks added a pair of defensive linemen on Friday, signing defensive end Ricky Ali'ifua and defensive tackle Lord Adusei-Hyeaman. Center Marcus Henry and defensive tackle Eddy Wilson were waived to make room on the 90-man roster.

Ali'ifua went undrafted in 2017 out of Utah State, where as a senior he led his team in sacks and tackles for loss. He signed with Kansas City as an undrafted free agent, then was waived prior to the start of the season. Ali'ifua signed a future contract with Cleveland in January then was waived later in the offseason.

Adusei-Hyeamang was a first-team All-Ivy League selection as a senior at Columbia, where he was a team captain and recorded five tackles for loss and 2.0 sacks. He initially signed as an undrafted free agent with the New York Jets.

Henry, who played at Bellevue High School, signed with the Seahawks as an undrafted free agent out of Boise State after taking part in rookie minicamp as a tryout player. Wilson also signed with the Seahawks as an undrafted rookie in May after playing collegiately at Purdue.
