Wales captain Sam Warburton has backed the Dragons to remain top contenders for the Rugby World Cup, despite the loss of Leigh Halfpenny and Rhys Webb.

Full-back Halfpenny and scrum-half Webb, both 26, are out of the tournament with injury, replaced by Eli Walker and Mike Phillips respectively.

Warburton told BBC Sport: "We've still got an absolutely fantastic chance to win the World Cup.

"If we want to be a side that wins the World Cup, it's got to be more than a 15 man team, it's a squad effort. So it's not a life or death situation."

Wales begin their World Cup campaign on September 20 at Cardiff's Millennium Stadium against Uruguay.
