Super League Show: Challenge Cup quarter-final preview

With four semi-final places up for grabs, BBC's Super League Show previews the last eight of the Challenge Cup.

Two ties - Warrington v Leigh and St Helens v Widnes - will be broadcast on BBC television across the weekend, while BBC radio has commentary of Hull KR's game with Catalans Dragons and Leeds' visit to Hull FC.

Of the eight teams involved, only 2007 finalists Catalans Dragons have yet to lift the trophy before.

Warrington v Leigh is live on BBC One on Saturday, 27 June from 14:30 BST.

St Helens v Widnes is live on BBC Two on Sunday, 28 June from 16:00 BST.
