Bradford Bulls v Hull. Clare Balding presents live coverage of the Challenge Cup fourth-round clash between Bradford and Hull. Kick-off at 3.00. Cup holders Hull began their path to glory last season with a comprehensive away win over Wakefield Wildcats at this stage and Airlie Birds coach John Kear will be hoping his team can produce the same form this year as they look to become the first team since St Helens in 1997 to successfully defend the trophy.
