Didn't Tell Them I Need Day Off, Should I Call In Sick?

Dear Experts, I got asked to go to a baseball game next Tuesday after the long weekend. I totally forgot to ask for the day off. I was going to just call in sick, HOWEVER, my friend just told me she heard about someone who was seen on TV at a game after he called in sick and got fired. Now I'm worried. What should I do? I paid for the ticket and it wasn't cheap - so I really want to go. But, I can't risk losing my job either. How can I fix this? Our Twitter Advice Project (T.A.P.) is no longer an active campaign.
