England play down World Cup fears as Kildunne ruled out of France decider

• Full-back misses Six Nations clash with hamstring injury
• Emma Sing to start at Twickenham on Saturday

England remain confident Ellie Kildunne will be fit for this summer's Rugby World Cup buildup after the joint-top try scorer in this year's women's Six Nations was ruled out of Saturday's grand slam decider due to a hamstring injury.

Kildunne, the World Rugby women's player of the year, has featured in all four games of England's campaign in their attempt to win a seventh successive title, but will be replaced by Emma Sing at full-back for the match at Twickenham against France, who have also won four out of four.
