If you'd like to get you son's name on the back of his jersey, you have a couple of options. You can take his jersey to Lawlors. They will need the jersey for 5 days and it will cost $5. Or you can take the jersey to Big Frogs (by Hy-Vee on 178 & Q), they will need to keep the jersey for 24 hours and it will cost $8.
If you have any questions, let me know.
