With rookie minicamp set to take place this weekend, the Seahawks added four non-rookies who will be eligible to participate in this weekend's workouts.
Signing Thursday were safety Joshua Moon, defensive tackle Walter Palmore, defensive end Marcus Webb and safety LaDarius Wiley.
Webb's name may be a familiar one to Seahawks fans, and he initially signed with Seattle last spring as an undrafted rookie out of Troy. Webb, who is 6-foot-2, 247 pounds, had 7.0 sacks as a senior for the Trojans.

Moon, who is 5-foot-10, 205 pounds, signed with the Jaguars as an undrafted rookie out of Georgia Southern in 2019, then was released prior to the start of the regular season. Moon, a three-year starter at Georgia Southern, started 12 games as a senior and led the team with 71 tackles. Also had two tackles for loss, one interception, three pass breakups and two forced fumbles.
The 6-foot-3, 317-pound Palmore, who went undrafted out of Missouri in 2019, signed with Houston as an undrafted free agent but was waived during roster cuts before the regular season. He played for the Houston Roughnecks of the XFL last year, then after that league shut down due to the COVID-19 pandemic, he signed to Dallas' practice squad. He was elevated for the Cowboys' Week 17 game against the Giants, then signed a reserve/future contract with Dallas after the season before being waived in May.
Wiley, who is 6-foot-1, 209 pounds, signed with the Titans as an undrafted free agent out of Vanderbilt in 2019, then was waived as part of Tennessee's roster cuts. As a senior at Vanderbilt, Wiley recorded 83 tackles, one interception and four forced fumbles. As a junior he led the Commodores with 88 tackles and had one interception, one forced fumble and five passes defensed.
