Clark set to miss Six Nations
England are likely to be without Calum Clark for the forthcoming Six Nations championship after the Northampton flanker damaged his right shoulder playing for his club at the weekend.
A statement from England Rugby said Clark would undergo surgery to his shoulder after he injured it during the Heineken Cup defeat against Glasgow Warriors on Saturday.
"It is a shame for Calum as he had worked hard to get back into the senior squad," England head coach Stuart Lancaster said. "But these things happen and our medics will work closely with Northampton on his rehab."
Clark, 23, who had only just returned to the England squad after serving a 32-week ban for breaking the elbow of Leicester hooker Rob Hawkins, is yet to win a cap for the senior team.
England host Scotland in their Six Nations opener on February 2.
