Maro Itoje is a doubt for England’s crunch Guinness Six Nations clash with Ireland at Twickenham on Saturday after becoming unwell overnight.

Itoje will miss Friday’s captain’s run at the stadium but England are “cautiously optimistic” that he will be available to take on Andy Farrell’s title rivals.
