Earlier tonight news broke The Rock was heading home without notice, causing Raw script rewrites.
Now more details have come out about what we would have seen had that not happened. PWInsider report that tonight’s episode would have opened with The Rock cutting a promo about losing the WWE Championship to John Cena at WrestleMania 29. This would then had led to Brock Lesnar and Paul Heyman coming out, and Lesnar beating down Rock. A future pay-per-view bout (likely at WrestleMania 30) would eventually have progressed from that.
That angle is now off. The site claims that one backstage source have told them that it it “chaos backstage”
