Vince McMahon tweeted on the match this weekend and referred to the pay-per-view having three main events.
Regarding Charlotte vs. Sasha Banks on Sunday, while there are some people in WWE that want the match to go on last, there are higher-ups who do not want the match to close the show, according to Bryan Alvarez on Wrestling Observer Radio.
There's a feeling that Sasha and Charlotte have to go on either first or last. Apparently they were actually discussing the risk of fans going home after the match if it takes place in the middle of the show because of Sasha being from Boston, according to Alvarez. If they put the match on first, there was a feeling that no one will leave because then they would miss most of the show.
There's no word yet on which match will be the true main event - Charlotte vs. Sasha, Rusev vs. WWE United States Champion Roman Reigns or Seth Rollins vs. WWE Universal Champion Kevin Owens.
