Due to the MLB Playoffs airing on FOX, WWE SmackDown will be moving to Fox Sports 1 on October 15 and 29.
The FOX schedule lists the American League Championship Series for October 15 and game 3 of the World Series will air on FOX on the 29th.
There is an ALCS game in between the 15th and 29th but that will air on FS1.
The WWE Draft is scheduled before the pre-emptions. At last word, per Andrew Zarian, WWE plans to do the draft on either 10/1 (SmackDown) and 10/4 (Raw) or on 10/4 (Raw) and 10/8 (SmackDown).
