Iowa says wide receiver Blake Haluska will miss his senior season and that receiver A.J. Jones and running back Barkley Hill have left the program.
Haluska, a Carroll, Iowa native, is out for next season with a shoulder injury.
He joined the Hawkeyes as a walk-on in 2010 and played in three games last year without making a catch.
Jones is from Dallas. He redshirted as a freshman last season.
Hill grew up in Denver, Iowa.
He missed the 2012 season with a knee injury and didn't play as a redshirt freshman in 2013.
