The Seahawks made changes to the roster Wednesday, waiving five players to help free up space on the 90-man roster for players drafted and signed as undrafted free agents last week.
Waived were center Drew Nowak, running back Cameron Marshall, tight end Ronnie Shields, defensive end Josh Shirley and receiver Tyler Slavin.
Nowak opened last season as Seattle's starting center before Patrick Lewis eventually took over the job, starting seven games. Marshall, who played previously in the Canadian Football League, Shields, Slavin and Shirley were all signed to future contracts prior to the start of the new league year.
The Seahawks began phase two of voluntary offseason workouts, hitting the outdoor practice field for the first time with their coaches since the end of the 2015 season.
