England play Northern Ireland in a World Cup Qualifier on Saturday 26th March, the same day as the Tigers v Valiants meeting at the KC Stadium. The England game kicks off at 3pm at Old Trafford, so City's game has been moved to a 1 o'clock kick-off.
Moving the game to the night before was not an option as the England Under-21s play Germany at the KC Stadium. Moving it back 24 hours was also ruled out as City have a game on the Bank Holiday Monday against Oldham.
