The belief is that the decision to have Drew McIntyre regain the WWE Title on Monday Night RAW was a last-minute decision by the company and was largely kept a secret prior to the match.
Dave Meltzer of the Wrestling Observer Newsletter noted that “all the key players involved prior to McIntyre beating [Randy Orton] on RAW were of the impression it was Reigns vs. Orton for the show.”
Meltzer added that Orton was possibly tipped off about the title change before others and would have known something by last week’s Smackdown when WWE started teasing Reigns vs. McIntyre.
