Wigan Warriors travel to Belle Vue on Sunday in the Powergen Challenge Cup, a reminder that the game has a 2pm kick off.
In the event of a draw after 80 minutes against Wakefield Trinity Wildcats the game will be taken into extra time.
This involves a period of ten minutes each way. Should the game still be drawn at the conclusion of this 20 minute period, the game will go to 'Golden Point' extra time, where the first points scored by any manner will conclude the game.
Meanwhile the draw for the Fifth Round will take place on Tuesday 4th April on BBC TV between 6.40pm and 6.50pm.
