Can my 11-year-old race online?

I created an EA account for him, but when I go to the "Connected Accounts" tab and try and set up the link to his PS account, I get this message: "We couldn't link your accounts. Your EA Account or your PlayStation™Network account is ineligible for linking."

Is there simply no way to link an EA account to a child Playstation account? He just wants to race against his friends.
