The Seahawks have signed first-round draft pick James Carpenter.
Carpenter, a 6-4, 321-pound tackle out of Alabama, was picked 25th overall in the 2011 NFL Draft.
According to several reports, the team also signed linebacker Leroy Hill, fullback Michael Robinson and defensive tackle Junior Siavii.
Hill has spent all six of his seasons with the Seahawks. Robinson and Siavii both joined the team last season.
