Harlequins Jack Clifford is out for the rest of the season
The back-rower will also miss England’s tour of Argentina.
Jack Clifford needs shoulder surgery and Harlequins have confirmed he will be out for 12 weeks.
The timeframe means he will be unavailable for the England tour but he should be back fit in time for the start of the 2017-18 season.
Harlequins director of rugby, John Kingston said: “While it is hugely disappointing for Jack to miss the conclusion of our season, the issue needed addressing immediately.
“I have no doubt Jack will do all that he can to get himself back to fitness and return all the better, and stronger for it.”
