During the Union's September 23 match against Chicago Fire, the team wore special Kick Childhood Cancer shirts during the team's procession.
The Union are now auctioning off those procession shirts for charity. Each player from the starting XI has their procession shirt in the auction. Fans can bid on the shirts here.
The auction extends until October 29, when bids stop at 8:59:59 ET. Proceeds for the auction go to the Philadelphia Union Foundation.
