Sick on tryout day. What should I do?

What Team ? Varsity/JV ?

What year are you ?

Did you play last year? (HS)

Does the coach know you ?

Go to the Dr. and get an excuse, sounds like you have the flu.

I am trying out for Varsity/JV, and I played Freshman last year.

I would say go to the Dr. tomorrow and get a written explanation as to what your illness is.

Take it to the coach ASAP and be guided by what the coach tells you.

Greening...would suggest you get in touch with Coach as soon as possible and let him know you are ill. If you played freshman ball they know what you can do.....in a sense you have been trying out for a year already.....so let the Coach know you are sick......and see what he says.....

GreeningJ,
I agree you should go to the doctor and get an excuse from school....this will also excuse you from all school activities. This protects you from unnecessary criticism from the coach or any rules you might violate.
Call the coach and explain your situation. This will impress upon the coach that you have desire and commitment and are serious about making the team.
Let me give you an example of how adversity can work for you. For 15 years I was a service technician with IBM. My job was to troubleshoot and solve customer’s problems with their IBM equipment. Some problems were very complex and could take days to resolve. Many times I felt as if the customers were ready to chew me out and throw me out the door ---but---- surprisingly these were the customers that would recognize my commitment and desire to solve their problems. These are the customers that would take the time to write a letter to my manager thanking me for my desire to solve their problem. ..... So, remember it’s not always what you accomplish that gets recognized, but your desire and commitment too!

Agree with everyone.

If you played last year, they know of you and your abilities.

Fungo is right...want to avoid criticism for violating some "rule" that the coach may have. Go to the doctor and follow through by having mom and dad contact the school/coach...just to be sure.

Unless someone unexpected comes in, the coach knows who his players will be and I'd guess that he has a good idea what his starting lineup will be on opening day.

Be sure to that him know of your status, I'm sure if you have what it takes, he'll keep you in mind. You just don't want him to think you decieded not to play.
