Rugby League Challenge Cup

Clare Balding presents coverage of the Challenge Cup quarter-final between St Helens and Warrington Wolves. St Helens are hot favourites to retain the trophy they won in 2006, but with the likes of Great Britain star Adrian Morley and mercurial half-back Lee Briers in their line-up, the Wolves certainly possess enough ability to cause an upset. Commentary comes from Ray French and Jonathan Davies.
