Survivor Series is just two weeks away and it will take place in a stadium for the first time in the event's history. The excitement among fans is at an all-time high and Triple H is pulling out all stops to make it a memorable event. Currently, four matches have been added to the card, including two WarGames matches and two championship bouts.Several other rivalries and storylines have been brewing on both brands, which have not made their way into Survivor Series. However, the card is still evolving with two weeks left until the annual event and there is a chance that WWE may add at least one more match to the PLE. It could be either a huge singles match or a big championship bout. Let's take a look at three matches WWE can add to Survivor Series after RAW:#3. Sami Zayn vs. Solo SikoaSami Zayn has been at loggerheads with Solo Sikoa for the past few months and this rivalry has reached a new height. Week after week, the MFT has been wreaking havoc on the roster, preying upon Shinsuke Nakamura, Rey Fenix and the Motor City Machine Guns, prompting multi-person brawls. However, Zayn might vow to put an end to this once and for all.Two episodes of SmackDown are left before the upcoming PLE and fans can expect the bedlam to continue. As a result, Sami Zayn could challenge Solo Sikoa to a one-on-one match at Survivor Series. Nick Aldis could make this match official now that Zayn is medically cleared to compete. This could shape up to be the fifth match on the card for the upcoming premium live event in San Diego.#2. AJ Styles, Dragon Lee vs. Los AmericanosEver since winning the World Tag Team Championship, AJ Styles and Dragon Lee have yet to feature in a major title defense. The two superstars have been involved in a back-and-forth scuffle with El Grande Americano's faction, Los Americanos, on Monday Night RAW. There is a slight chance that WWE could book the two teams in a title match at Survivor Series.Styles and Lee may be forced to defend their gold against Los Americanos. Adam Pearce could make this match official next week on the red brand, adding the World Tag Team Championship clash to the upcoming spectacle. This will help WWE put all superstars in the spotlight while booking another championship defense at the annual event.#1. Ilja Dragunov vs. Tommaso Ciampa may get added to Survivor SeriesIlja Dragunov has been issuing open challenges every week on SmackDown, defending the United States Championship. However, the one name that he has been evading is Tommaso Ciampa. The two superstars have been at loggerheads for the past few weeks, but WWE has kept Ciampa and Dragunov away from a match for now, preventing a collision between them.The company could be setting up the stage for a massive championship match between The Blackheart and The Mad Dragon. Tommaso Ciampa could unleash a brutal attack on Ilja Dragunov on an upcoming episode of SmackDown. As a result, Nick Aldis could book the two superstars in a United States Championship match at Survivor Series.
