I was asked my dad about this. He was at both of the games. He said in the Metrodome the refs called a timeout because the Iowa fans were making too much noise. Hayden Fry walked onto the field and motioned for the crowd to quite down so they didnt get penalized. The smart Gopher fans then started making noise to get Iowa the flag. Fry ran onto the field and pointed out to the refs who was now making the noise and they picked up the flag.
