Another week, another invasion from NXT - and a familiar foursome caused havoc in Philadelphia last night.Ever since WWE's third brand was drafted in to save SmackDown two weeks ago following the issues in Saudi Arabia that saw most of WWE stranded 14 hours away from the States, we've seen NXT stars on the main roster on a regular basis.There was a great reaction to the NXT takeover and two superstars who have featured prominently are the two main champions - Adam Cole and Shayna Baszler.Cole has faced both Daniel Bryan and Seth Rollins in main event television matches, whilst Baszler has attacked Bayley multiple times as she prepares to face her and Becky Lynch in a battle of the champions.Baszler showed up again last night but she was dropped by Sasha Banks, before three of her WarGames opponents in Rhea Ripley, Tegan Nox and Mia Yim, along with Dakota Kai, came as back-up in aid of the NXT brand [not because of Baszler - they are feuding on Wednesday nights after all].

It led to a huge brawl with the SmackDown women's division, and an eight-woman tag match eventually happened with Nikki Cross picking up the win for Team SmackDown by pinning Kai - potentially a sign of things to come at Survivor Series.

Earlier in the night though, NXT invaded yet again during a Tag Team Championships match between champions The New Day and The Revival.

Just as it seemed like the match was going to reach its final stages, Undisputed Era attacked all four participants in the match, brutalising them with a series of finishers.

It was only when the cavalry arrived from the locker room that they scarpered, but the dangerous foursome clearly sent another message to the blue brand that they mean business going into Survivor Series weekend next week.

Three of the four have matches locked in for Sunday's show-piece, just 24 hours after they will contest their third WarGames match in consecutive years.

Cole doesn't have a Survivor Series match yet but it's highly likely that he'll be part of Team NXT against Raw and SmackDown - a match that could be a classic.
