England could be without Manu Tuilagi for the entire RBS 6 Nations after the Leicester centre was ruled out until February with a chest injury.

It was hoped the torn pectoral muscle sustained on Aviva Premiership duty in September would heal without surgery and that he would return to action by next month.

But the 22-year-old has been forced to undergo an operation to have the damage repaired, placing his involvement in the Six Nations in jeopardy.

"Manu is probably out for three months," Leicester director of rugby Richard Cockerill said.
