It's the 5th round of rugby league's Challenge Cup this weekend.
The trophy has been on tour and it paid a visit to Castleford earlier this week.
Former teammates Mark Aston, coach of the Sheffield Eagles, and Daryl Powell, the Castleford coach, who both won the trophy as players with Sheffield in 1998, will do battle on Sunday for a place in the quarter finals.
On Sunday evening at the John Smiths Stadium in Huddersfield, Hull FC take on Warrington Wolves in the semi-final of the Tetley's Challenge Cup. The prize for the winners is a place in the final at Wembley. Chris Dawkes looks ahead to the big game.
