Wasps flanker James Haskell faces an intensive period of rehab if he is to be fit in time for England’s Calcutta Cup clash with Scotland.

The 22-year old had an MRI scan on Tuesday that revealed he had injured the posterior capsule on his left ankle, which rules him out of Wasps’ visit to Newcastle on Friday.

But he has begun an intensive recovery programme and could return in time for England’s trip to Murrayfield on March 8th.
