Just yesterday, Kofi Kingston tweeted the following:
Flew home to witness the final stages of my procreational efforts! (Any day now). I'm sure the boys held it down! https://t.co/n1RuESE6QP

It was later confirmed that WWE allowed him to fly home to be with his wife as they welcome their child into the world. Considering there are only a couple days left of it, it's safe to assume he's off the remainder of the tour.
