NFL bans Mardi Gras Port-a-potties???

According to this article they have.
When Worlds Collide

"When I made it to the parade route and went to use the porta-potties that are always there I noted that there were none. I was rather surprised as this is the first time in the few years I have been shooting Mardi Gras that there were no porta-potties. Checking in with one of the city workers I was informed that the NFL said they couldn’t have any porta-potties until after the Superbowl."

I find that hard to believe. Anyone know anything about this?

Oh yes, he also saw Sean Payton at Saints Headquarters.
