NFL 'fanny packs' aren't for carrying

QUESTION: I’m baffled by the fanny packs Jay Cutler and other Denver Broncos were wearing during the game against Seattle. The fanny packs were slid around to their backside. I think some of the Seahawks had them too. What do they carry in them?

ANSWER: They’re hand warmers. When the players are on the field they usually slide them around to the back. Broncos spokesman Paul Kirk said the players would not be allowed to carry items in a fanny pack onto the field.
