The team said Thursday that a pregame ceremony is also planned for Sept. 1. Caray's wife, Dutchie Caray, and Cubs chairman Tom Ricketts are expected to be at the rededication.
Caray's statue will be rededicated at Sheffield and Waveland avenues. It previously was outside the field at Sheffield Avenue and Addison Street, where a new statue of Cubs outfielder Billy Williams will be placed.
Team officials say Dutchie Caray will throw a ceremonial first pitch before the game against Pittsburgh. She'll wear a No. 23 Caray jersey.
