Fox, which airs SmackDown on Friday nights, released their schedule for TV sports in October.
Based on the released schedule, it looks like they will not be airing SmackDown on October 23. What will be airing instead is the Major League Baseball World Series.
There has yet to be a new schedule released by Fox or the WWE for the October 23 episode of SmackDown. It should be pointed out, however, that this was also what happened last year.
Last year, the episode that coincided with the World Series was instead aired on Fox Sports 1.
