A friend of mine is going to let his medical lapse and then fly his
PA-11 under the sport pilot rules. From what both he and I have
researched there is no certifcate issued from the FAA that says you are
a sport pilot. What does a person have to carry when operating under
sport pilot rules, just a drivers license?

This might have been assumed in your post - but he also has to carry his
recreational or better pilot certificate.
