KDKA-TV is reporting that sources have told the station that U2 will close out its 2011 tour at Heinz Field on July 26. The report says that former Steelers chairman and U.S. Ambassador to Ireland Dan Rooney is a fan of the band and has been working to get a concert here. U2 was forced to cancel shows earlier this summer due to Bono’s back surgery, but is back in action now.
