Advice needed!

I just realized my baby shower is scheduled for the same day as the Super Bowl! I really wanted a coed baby shower. We got a big venue and catering for 100 people but now I’m worried its going to conflict with super bowl plans. I spoke to the venue and they said I could it out a week. But I already sent out invitations! Should I change it? Do I have to remake and resend invitations completely? What should I do?
