According to sources, there was a major meeting backstage about an hour or two before the Brock Lesnar vs. Randy Orton WWE SummerSlam pay-per-view event started. The meeting was to talk about the finish of the match and was attended by Triple H, Mark Carrano, Brock Lesnar and Paul Heyman. As of now, there is no word yet on whether Orton was there, but it would make sense.
Of course, the finish of the match saw Lesnar assault Orton and leave him down in the ring. This was heavily debated beforehand and discussed and negotiated before the match.
