The Seahawks added defensive line depth a day before the start of training camp, signing veteran defensive tackle Earl Mitchell. Seattle also added Daniel Williams, a receiver who went undrafted out of Jackson State in 2017.

Mitchell, 31, started 28 of 30 games played for the San Francisco 49ers over the past two seasons. A third-round pick in 2010, Mitchell spent his first four seasons with the Houston Texans, then the next three with the Miami Dolphins before signing with San Francisco in 2017.

Mitchell, who had 61 tackles, one sack and four passes defensed over the past two seasons with the 49ers, provides depth for a position group that will be missing starting defensive tackle Jarran Reed for the first six games of the season due to suspension.

Williams, who had 184 catches for 2,497 yards and 19 touchdowns during his career at Jackson State, initially signed with the New York Jets as an undrafted rookie, and has also spent time with Washington and Cleveland.

The Seahawks waived a pair of undrafted rookies who signed earlier this year in order to make room on the 90-man roster, running back Marcelias Sutton and cornerback Derrek Thomas.

The Seahawks also placed safety Lano Hill on the physically unable to perform list, and receiver Caleb Scott on the non-football injury list. Hill finished last season on injured reserve after sustaining a hip injury in the final game of the regular season. Scott had surgery for a foot injury sustained working out in the offseason. Unlike in the regular season when players on those lists have to sit out a certain number of games, players can return from PUP or NFI at any time in training camp.
