Harlan and John Jones made the comments while attending the National Football League owners meeting in Phoenix.
Lambeau Field's capacity jumped from about 61-thousand to nearly 73-thousand with the stadium renovation. The Packers have sold out every home game in Green Bay since 1960. There's a season ticket waiting list of approximately 71 and a-half thousand.
Jones says there are no plans currently to expand Lambeau, but team executives think about what it will take to remain competitive over the next decade and beyond.
