Instead of the result show of AGT WNBC is broadcasting a pre-season football game. This does not mean you cannot watch AGT. The WNBC substation will air it. Antenna users can tune to channel 4.2. FIOS users can select channel 460. Comcast users do have this channel but since I can't remember what it is you will have to look in the guide. The other option is to wait until Sunday when WNBC will air the show. Although it may be available online before then.
