USC at Arizona 9/29/2018
In this Sept. 29, 2018, photo, Nebraska wide receiver Kade Warner (81) stands with teammates during a time out in the second half of an NCAA college football game against Purdue in Lincoln, Neb. Warner, a walk-on redshirt freshman and son of NFL Hall of Famer Kurt Warner, has ascended to the top of the Nebraska depth chart at wide receiver. He was a standout receiver for his high school in Scottsdale, Arizona, but didn't attract much recruiting attention. He chose Nebraska over a scholarship offer from the University of San Diego and preferred walk-on offers from several schools, including Arizona State University, UCLA, Northwestern and Iowa.
