Round 4
- (week ending 1 April)
This round saw the teams from the Super League enter. The only all-Super League match saw Warrington defeat Hull KR. Celtic Crusaders' defeat saw the final Welsh team leave the tournament. Once again, however, all games went to form, with no sides from lower leagues defeating a team from a higher league. Pia's defeat saw the French rugby league championship's exit from the Cup.
