J Cole was supposed to be on stage at the Palace of Auburn Hills on Sunday July 23rd, but the show has been bumped back a couple of days.

In total, three of J Cole's upcoming concerts were forced to move, and his Chicago show has been cancelled outright.  A press release from tour management rolled out the changes this morning.

Due to transportation issues at the Canadian border, the following J. Cole shows are being amended.Tickets are valid for the new date in each city and refunds are available at point of purchase. We apologize for the inconvenience. Detroit at The Palace of Auburn Hills is rescheduled from Sunday, July 23 to Tuesday, July 25 (Refunds available until July 23)

So if you were planning on going to the show Sunday, you have a couple of options.  You can use your tickets for the rescheduled show on Tuesday or you can get a refund.  If you decide to get a refund, you have to do it before July 23rd.
