Five pairs of Oregon Air Jordan shoes and a Nintendo Wii gaming console were also stolen from his residence.
Frost was hired by Nebraska in December. He started at quarterback for the school in 1996 and 1997, leading the Huskers to a 24-2 record.
He coached in a variety of roles at Oregon from 2009-15 before joining UCF as head coach from 2016-17.
The burglars apparently entered Frost's home, which is being renovated, through an unlocked garage door.
