Challenge Cup: Widnes captain Jon Clarke targets Wembley swansong

Widnes captain Jon Clarke tells BBC Sport that leading the Vikings in a Challenge Cup final at Wembley would be the perfect way to end his career.

The 35-year-old is to quit the sport at the end of the season and, speaking ahead of Sunday's semi-final against Castleford, the former Warrington hooker says it would be a special way to bow out.
