The rule still applies that players are allowed to participate in a division with an age range up to two years older than their age group; so while the official age range for U11 is 8/1/12 - 12/31/13, players with birthdays as late as 12/31/15 are allowed to be rostered (we just don't always recommend that large of an age gap, depending on the age group and player there can be a significant difference in size or level/physicality of play).
Eric–yes, you're good for U11!
