Unless WWE prepares a one-hour edition of Friday Night SmackDown, there is no way UPN could air the show on Friday night. Specific plans for the show are not yet known, however, as UPN’s press release made no mention of preemptions.
Interestingly enough, there are plenty of opportunities for UPN to air SmackDown. Because its fall schedule – other than the WWE show – does not kick off until 9/19, UPN can theoretically air the first “Friday” edition of SmackDown! on Thursday the 8th or Thursday the 15th.
Expect a further update regarding this story shortly.
