The Priestley Cup semi-finals will go ahead on schedule this Sunday despite England reaching the World Cup final.
League officials met tonight and ruled the show must go on as there is no scope to delay the ties and get the competition completed on schedule.
"We are delighted that England have reached the World Cup final against New Zealand but we have no scope to adjust the schedule of our premier competition and therefore have ruled that both ties must go ahead as planned," a league statement said.
Hanging Heaton, who visit Woodlands in Sunday's semi-finals, have a particularly busy schedule.
They have a rearranged Premier Division to play at Bradford & Bingley on July 21 before starting their defence of the Vitality Clubs T20 Cup in the Regional final at Bllingham Synthonia on July 28.
The match with Bradford & Bingley has had to be rearranged because the Bingley Live Music event is to be staged at Wagon Lane on August 30 with a crowd of 8,000 expected, the date when the game was due to be played.
A league statement said: "Due to health and safety concerns it is not possible for the match to be played at Wagon Lane on August 30. This event was only switched to Wagon Lane once the season was under way so discussion had to be held between the two clubs to find an alternative date.
"This was a situation we have never been confronted with before and we thank the two clubs for assisting us in finding a resolution to the problem."
