UPDATE: The Packers have now released an updated statement, saying they will not use such displays in the future.
“The banner used during Sunday’s pregame ceremony supplemented the three U.S. flags on the roof of the stadium and the flag carried by the color guard on the field. We've used such displays from time to time in the past when other pregame elements take up a significant portion of the field. To avoid causing confusion, we will not be using such displays in the future.”
PREVIOUS REPORT:
There appears to be some confusion over a banner "flag" unfurled on Lambeau Field before Sunday's game.
I always find this so weird. Maybe there is a reason for it but that’s not our flag. I don’t get it. pic.twitter.com/gPG2yogqPK
