Witthoft conceded his son was starting to become more concerned about his appearance after the jersey barely came down to his belt line.
Witthoft first gained national attention three years ago, and attended his first Packers game in December. He's also planning to attend the Sept. 8 game when the Packers retire Favre's No. 4.
His mother, Carolyn, had washed the jersey every other day and mended it when needed.
