The start of the 2018 college football season also meant the return of one of the sport's greatest traditions.
Prior to Saturday's kickoff between Northern Illinois and Iowa, fans, players and officials in Kinnick Stadium turn to deliver the "Iowa Wave" to the University of Iowa Stead Family Children's Hospital.
The hospital, which opened last year, overlooks the stadium and has a special section on the top floor where patients and their families gather to watch the game.
Per Sports Illustrated's Emily Caron, the wave began last year after the first quarter of the season opener against Wyoming when the public address announcer asked fans in attendance to wave at the fans watching from the hospital.
