England's Billy Vunipola set to miss Six Nations with knee injury
Saracens number eight undergoes surgery following 27-14 victory over Argentina at the weekend

England number eight Billy Vunipola is likely to miss the Six Nations after being ruled him out for at least three months with a knee injury sustained in Saturday’s win over Argentina.
Saracens’ Vunipola, 24, had surgery on Sunday to repair the torn cartilage he suffered in the 27-14 victory over the Pumas and will not be fit before the Six Nations starts on February 4.
“Billy’s been absolutely fantastic for England over the last 11 months and we wish him a quick recovery,” said England head coach Eddie Jones.
“He’s a very influential player in the set-up and there’s no doubt he’ll be missed for the game against Australia.”
England are looking to seal an autumn series clean sweep when they face Australia on Saturday at Twickenham after earlier victories against South Africa, Fiji and Argentina.
