Ellie Kildunne ruled out of England's Rugby World Cup quarter-final after head injury

• World player of the year will miss game against Scotland

• Full-back suffered concussion symptoms after tackle

The England full-back Ellie Kildunne has been ruled out of the team's Rugby World Cup quarter-final against Scotland next Sunday because of concussion protocol.

It was confirmed after the Red Roses' win over Australia that Kildunne did not have a head injury assessment as she was immediately removed with concussion symptoms after hitting her head on the ground following a tackle. That means that the reigning world player of the year has to have a 12-day mandatory stand down period.
