TWO of the Powergen Challenge Cup quarter-finals are to be shown live on Grandstand.

Widnes Vikings take on Super League runners-up Bradford Bulls on the BBC at 2.45pm on Saturday.

Leeds Rhinos' home tie against Hull will be televised the following day (12.10pm).

The other two quarter-finals - Salford against Super League champions St Helens and Swinton's tie with holders Wigan - will also be played on Sunday.

Swinton travel to Wigan's JJB stadium for the match because Moor Lane only has room for 2,500 fans.

The Rhinos game was originally scheduled for Saturday but Yorkshire police could not provide safety guarantees as Leeds United and Bradford City football clubs are at home that day.
