Guwahati, Oct. 28 -- England remain optimistic about star spinner Sophie Ecclestone's return for their Women's World Cup semi-final clash against South Africa at the Barsapara Stadium in Guwahati, scheduled to take place on Wednesday.

Ecclestone, the fifth-highest wicket-taker with 12 scalps in six appearances, landed awkwardly on her left shoulder while attempting to stop the boundary on the second ball of England's 8-wicket win over New Zealand in their final group stage game on Sunday.
