Seahawks coach Pete Carroll said Monday that running back Travis Homer was "really sore" after leaving Sunday's game with a rib injury, and on Wednesday, Homer was placed on injured reserve, meaning he will miss at least the next four games.
Cornerback Xavier Crawford was signed off the practice squad to fill the open spot on the 53-man roster. Crawford has been elevated from the practice squad to play in each of the past two games, playing 15 snaps on special teams.
The Seahawks also added backfield depth to the practice squad with Homer out, signing running back Godwin Igwebuike and fullback Cullen Gillaspia.
Igwebuike, who went undrafted out of Northwestern in 2018, has appeared in 23 career games, including all 17 with Detroit last season when he rushed for 118 yards and a touchdown on 18 carries while also catching seven passes for 60 yards. Prior to last season, Godwin was a safety before the Lions converted him to running back. Godwin also spent time with the XFL's Seattle Dragons.
Gillaspia, a 2019 seventh-round pick out of Texas A&M, has appeared in 38 games over three seasons with the Texans and Giants, playing primarily on special teams.
Safety Scott Nelson was released to make room on the practice squad.
