Robshaw out of Six Nations
Robshaw will undergo surgery on his left shoulder on Monday to repair an injury sustained in a Premiership match against Worcester Warriors on New Year's Day.
He is expected to be out of competitive action for around 12 weeks.
Robshaw's absence will be a blow to Eddie Jones' plans for the Six Nations.
The England coach has a number of players already on the sidelines, which includes props Joe Marler and Mako Vunipola.
James Haskell and George Kruis are also concerns – while Billy Vunipola is a long-term absentee.
Haskell was forced off the field during Wasps' 22-16 victory over Leicester Tigers on Sunday after getting a bang on the head after a powerful tackle on Leicester's Freddie Burns.
He'll have to pass all return to play protocols before being cleared to play for Wasps or England.
