Yes, Donald got in touch with RTR a few years ago and confirmed that because he had tweaked a muscle at Old Trafford a few days before, he had been unable to referee the game at Bradford and Norman Glover had taken his place. The match day programme was not changed in time and so named Don as the referee, and I saw a local media report that he had received some hate mail as a result of what happened at Valley Parade which, even if he had been in charge that day, was obviously totally unacceptable.
