As we all know by now, SmackDown Live is scheduled to air every Friday nights on FOX beginning October 19th, 2019, but it looks like there could be more WWE programming that will be aired on The FOX Networks.
According to Richard Deitsch of The Athletic, there is said to be a very good chance that FS1 will air a SmackDown pre-show each Friday night. There is also talk of FS1 hosting post-shows following major WWE PPV Events, such as SummerSlam.
Regarding on-air talents for the potential WWE pre-shows and post-shows on FS1, Deitsch noted that the talents would be hired by FOX but there would likely be some kind of approval from WWE.

It was previously reported that there was talk of doing a weekly WWE studio show on FS1, perhaps on Wednesday nights.
