My quandary is not how this could have happened but rather why the FTA did not order a replay of this match after it was determined that the team was legal and a procedural error was made.

If they were under a time crunch, I could understand.

It would also depend on when the red card was issued. If it was issued after the match, I would guess that there is a way to go in and remove it in the scoring system, should that be judged necessary--it would take a while to show, though. If it was issued before the match, then a replay would be the only way to fairly deal with the issue. Unfortunately, due to time constraints, replays are somewhat tricky to fit in.

I wonder if the field crew didn't see the inspection sticker indicating "passed". If they had seen it, then they certainly should have called the inspection team for confirmation when this came up. It sounds like they saw the radio and said "Oh, the inspectors made a mistake" and issued a red card. (Whether you think that's a good call based on <S04> is up to you.)
