This Sunday's Survivor Series card has undergone an unbelievable amount of changes over the past ten days or so. AJ Styles will now face Brock Lesnar, The Usos are no longer facing The Shield, Triple H took Jason Jordan's place on Team Raw, and now Alexa Bliss will have to face Charlotte Flair instead of Natalya. Now that everything is done and dusted, the late changes are over with right? Wrong. Charlotte winning the SmackDown Women's Championship on Tuesday night means that her slot on Team SmackDown is now vacant. It's a five-on-five match and Team Blue only has four Superstars. WWE is yet to reveal who will fill that fifth and final spot, but here are five women who they could opt for on Sunday night.

The most obvious choice for the role is of course Natalya. Charlotte has taken the Queen of Harts place in the champion versus champion match, so a quick fix would be to slot Nattie right into the vacancy left by the new champion. Despite the slightly annoying character Natalya has portrayed since becoming champion—and before that to be brutally honest—she hasn't distanced herself from the rest of the women. There's no reason why captain Becky Lynch wouldn't recruit her to make up the numbers and there is a very real possibility that could happen. It's the most obvious option so it will more than likely be the one WWE decides to go with. Leaving Nattie off the card seems pretty harsh at this point.

4. Lana

Another woman on the SmackDown Live roster currently with nothing to do at Survivor Series—aside from accompanying Tamina to the ring—is Lana. When General Manager Daniel Bryan first assembled his women's team he threw something of a slight Lana's way. There were six women in his office and Bryan said that all five women in the room would make up Team Blue. When Lana pointed out that there were six of them Daniel chuckled and said that he obviously wasn't including her in his statement. Pretty harsh, especially considering how much The Ravishing Russian wants to compete in the ring judging by her comments on Total Divas so far this season. Now that a spot has freed up she might get her chance. Plus multi-person matches seem to be something WWE are occasionally OK with Lana competing in.

3. Michelle McCool

This entry may seem a little out of left field, but it isn't completely out of the realms of possibility. Michelle McCool has been away from WWE and pro wrestling entirely since 2011, but recently expressed an interest in returning to the ring. It's pretty ironic considering her husband The Undertaker may have just given up on competing earlier this year. Michelle recently had an interaction with the new Women's Champion Charlotte on social media. It began when McCool complimented the champ on her recent book, Second Nature. That prompted Flair to reply, jokingly attempting to coax Michelle out of retirement in the process. It turns out she has been waiting for someone to ask and claimed that if WWE calls her, she'll answer.

2. Ronda Rousey

Now, if you thought the Michelle McCool idea was pretty out there, then you will likely think that this suggestion is downright silly. Ronda Rousey is well and truly on her way to competing inside a WWE ring, so why not at Survivor Series? Well, there is a simple answer to that, because she isn't ready yet. If reports are true, then Rousey has only just started training at WWE's Performance Center. It isn't as if the Survivor Series match is a one on one affair though. Rousey wouldn't necessarily need to do much aside from pull off a couple of simple moves and throw an armbar on a lucky lady or two. It would certainly further the rivalry between her own Four Horsewomen and WWE's take on the faction.

1. Paige

Let's be honest, despite what has come previously in this list this is the one that everyone is expecting. Paige is supposed to be returning to WWE after over a year away any day now. In fact, we thought we would have seen her by now. The former Divas' Champion has been training at Full Sail and was backstage for this week's Raw. A lot of fans were actually pretty disappointed that she didn't make an appearance on Monday. Well, maybe that's because Paige won't be a Raw Superstar when she returns, she'll be a member of the SmackDown Live roster. There are rumors that WWE is holding off on Paige's return until after Survivor Series so that all the focus is on Asuka come Sunday night. Whether that's true or not will become clear at Survivor Series.
