Iowa star tight end Erick All out for season with leg injury

All, Iowa's leading receiver, was injured in Saturday's game against Wisconsin.
The injury worsens the Hawkeyes' issues on offense, as their starting QB is also out for the year.
All was expected to be a key part of Iowa's passing attack this season.
The tight end position has been hit hard by injuries for the Hawkeyes this year.
Iowa will need to rely more on its running game and defense going forward.
