GREEN BAY, Wis. (CBS 58) -- Do you have any guesses as to what Aaron Rodgers' Halloween costume will be this year? 

The MVP made an appearance on the Pat McAfee Show Tuesday, Sept. 21, and mentioned he is growing out his hair for this year's costume. 

"I have a month-ish until Halloween. This has been a year in the making for my costume. I'm not going to give it away but it's someone who has been a hero of mine who has long-ish hair."
