Castleford Tigers and Huddersfield Giants must hold nerve after going down untested route
As the eight Challenge Cup quarter-finalists gear up for the biggest weekend of the season to date, the rest of their Super League rivals face a period of soul-searching.
Wigan Warriors are facing up to their trophy defence being over after succumbing to a remarkable fightback by Hull FC in round four.
The early exit will sting the Warriors, a club that have known nothing but success in recent times.
It has been five long years since fallen giants Leeds Rhinos last got their hands on silverware or even reached the quarter-finals of the cup.
While the draws have not been kind to the Rhinos, better is expected of one of the most successful clubs of the summer era.
