WWE has again changed the main event for tonight's SmackDown Live with just hours to go before the show emanates from the FedExForum in Memphis, TN.

The new main event is now a non-title Champion vs. Champion match with WWE United States Champion AJ Styles going up against WWE Champion Kofi Kingston.

Luke Gallows and Karl Anderson will be at ringside with AJ, while Big E and Xavier Woods will be at ringside for Kofi.

We reported earlier that Vince McMahon made major rewrites to today's episode with the original plan of Big E and Woods vs. Elias and Drew McIntyre being nixed in favor of a six-man tag match with The OC vs. The New Day, but it appears there have been further changes.
