From Chris Cornell’s official Facebook:
Chris Cornell regrets to announce that he will be unable to perform tonight at the Grand Opera House in Wilmington, Delaware, due to a severe shoulder strain sustained today.
Chris had hoped to be able to make the show tonight, but doctors have advised that he rests. The date will be rescheduled as soon as possible, and all tickets will be honored. Chris would like to apologize to everyone, especially those who have traveled to Wilmington for the show.
We here at AltNation wish Chris a healthy and speedy recovery.
