It appears that New York Red Bulls II (the New York Red Bulls reserve squad that competes in USL) will be playing Newtown Pride FC at Bridgeport's Harbor Yard on July 30th at 7:30 p.m..
The Red Bulls have yet to publicly confirm whether they will be taking part in the match. As seen above in the embedded tweets, ticket details have not yet been released but will "be on sale soon."
Newtown Pride FC play in the First Division of the Connecticut Soccer League (USASA).
The Newtown Pride played a charity exhibition match against the New York Cosmos (NASL) in 2013 at Veterans Memorial Stadium in New Britain, Connecticut, losing 6-0. Proceeds from ticket sales went to the Newtown Parent Connection which "hoped to finance a wellness, prevention and recovery support infrastructure for the Newtown Community" following the shootings at Sandy Hook Elementary School.
