Whitehaven have had to change their home fixture with York City Knights, originally scheduled for Sunday June 18.
The Knights are still involved in the Challenge Cup and will be playing their quarter final tie with Leigh Leopards on that date.
The game will now be played at the LEL Arena, Whitehaven on Wednesday, June 28 with a 7.30pm kick-off.
Whitehaven scored a fine win at York earlier in the season so will be going for a Championship double over the Knights when they finally get to grips.
