According to Dave Meltzer on a recent edition of The Wrestling Observer Radio Program, The Ronda Rousey vs. Natalya Match that aired on this week’s taped RAW was called completely in the ring. In other words, the two did not practice or rehearse beforehand and basically went through their spots by calling them as the match progressed.
On a related note, it is unclear if the originally planned storyline between Rousey & Natalya is still going to happen. There was a decision made to drop the angle after Jim Neidhart’s death, but with Natalya losing to Rousey, WWE has an opportunity to come back and do it again except this time Natalya would snap after losing and turn on Rousey. Meltzer speculated that if WWE wants to go back to this plan, it might not happen until the later part of 2019.
