Clare Balding presents coverage of the Challenge Cup quarter-final between Bradford Bulls and Huddersfield Giants at the Grattan Stadium, Odsal. The Bulls have a proud tradition of Cup success in recent years, winning the competition in 2000 and 2003, and they will be favourites to put home advantage to good use here and book their passage into the semi-finals. But the Giants will not be overawed by the prospect of this fixture and have happy memories of playing at this stadium, having shocked Leeds Rhinos here in the 2006 semi-final. Much will depend on whether the Giants can contain Bradford's blockbusting winger Lesley Vainikolo, who is making one of his final appearances before switching codes to rugby union with Gloucester. Commentary comes from Dave Woods and Jonathan Davies.
