Interesting that the fourth official took over for the last few minutes - would love to know what conversations happened there. Can't ever remember a referee being removed mid-match due to performance before.
He didn't. He was due to take over for the final few mins & any TAO but as one of the teams refused to come back out that never actually got played. Interesting though that he was due to do it, had it happened. I agree I can never remember a referee 'substituted' due to performance.
