How long will each match be at SummerSlam?

#12 WWE Championship: AJ Styles (c) vs. Samoa Joe (~14 minutes)

Round 1.

Since it's a WWE Championship match, we can expect around 14-15 minutes, even if the build to it has been lackluster. With those advertisements for Hell in a Cell, we can also expect that this won't be the last meeting between these two.

A good few minutes of action to build up the next match can be expected. Though it probably won't be the match of the night, it should still be one of the better contests, even with Styles' diminished 2018 CV.
