Semi-final: St Helens v Huddersfield Giants

Clare Balding hosts live coverage as St Helens and Huddersfield meet at the Halliwell Jones Stadium in Warrington in the second of the Challenge Cup semi-finals. St Helens have won the trophy for the last three years and are hot favourites to land a fourth at Wembley. But Saints will be without one of their key players, Sean Long, and they will face a Huddersfield side who have been in impressive form in 2009's Super League. Commentary comes from Ray French and Jonathan Davies.
