Huge Change Made To WWE Evolution Pay-Per-View

WWE Evolution is coming up soon and it looks like as WWE got closer to the big show something might have been off about how they initially booked things. Because it seems that the card went through a huge change tonight on Raw.
WWE had announced Alexa Bliss vs Trish Stratus and Mickie James vs Lita in singles matches. But this week on Raw, Trish came out and started cutting a promo only to be interrupted by both Bliss and James.
The heels came down and after exchanging words, they ended up challenging Trish to a tag team match. Then Stratus introduced her partner who happened to be Lita. The Queen Of Extreme came down and they ran the heels off.
Now their two singles matches is one tag match so it will be Alexa Bliss and Mickie James vs Trish Stratus and Lita at WWE Evolution.
