The Seattle Seahawks confirmed the earlier report from FOXSports.com's Adam Caplan and announced the addition of linebacker Alvin Bowen.

In addition to Bowen, the Seahawks have also signed Nick Tow-Arnett, a 6-3, 242-pound fullback/tight end from the University of Minnesota. Tow-Arnett did have a carry during his college career, but caught 57 passes for 865 yards and four touchdowns for the Gophers, including 37 receptions for 505 yards and 3 scores in 2009.

Not coincidentally, Seahawks quarterback Jedd Fisch was the Gophers' offensive coordinator in 2009.

Tow-Arnett signed with the Dallas Cowboys as an undrafted free agent, but was cut after the Cowboys completed their off-season workouts on June 22.

To make room for Bowen and Tow-Arnett, the Seahawks waived undrafted rookie guard Adrian Martinez and "waived/injured" fullback Ryan Powdrell.
