Ben Youngs and Ollie Lawrence withdraw from England's training camp

Scrum-half Youngs picked up a minor thigh injury in Leicester Tigers' win over Gloucester, while Worcester Warriors centre Lawrence, 22, is unwell.

The injury to 32-year-old Youngs is not expected to rule him out of Leicester's game against Saracens on Saturday.

England are preparing to face Tonga, Australia and South Africa in November.

Eddie Jones announced his 45-man England squad a week ago with big names such as Billy and Mako Vunipola, Jamie George and George Ford all left out.

Youngs ruled out of Six Nations

The Leicester Tigers scrum-half was taken off early on in Rome on Sunday, his evident pain souring what proved to be a commanding 46-15 win for England.

And on Monday the Rugby Football Union (RFU) confirmed the 28-year-old had ruptured the medial collateral ligament in his left knee, bringing an end to his tournament.

Youngs will undergo a further assessment with a surgeon later this week, but the RFU said he could be sidelined for up to four months.
