Iowa's three starting linebackers headline the program's leadership group for 2013.
The Hawkeyes announced the group of 15 players on Wednesday.
The group's members, who are voted on by the players, perform the duties of captains.
Senior linebackers James Morris, Christian Kirksey and Anthony Hitchens are joined by fellow seniors B.J. Lowery, Brett Van Sloten and guard Casey Kreiter.
Juniors include wide receiver Kevonte Martin-Manley and Mark Weisman, and four sophomores were voted on by their teammates.
Sophomore quarterback Jake Rudock and redshirt freshman quarterback Casey Beathard also made the list.
Iowa opens the season on Aug. 31 when it hosts Northern Illinois.
