All three of the scrum-halves in the squad suffered knocks against Georgia, so Wood's flown out as cover.

He's not actually in the squad yet, but if any of the injuries turn out to be serious he'll take their place.

Should Matt Dawson, Andy Gomarsall and Kyran Bracken win their fitness battles then Bath player Wood won't be needed, so will fly back to the UK.

Forwards Richard Hill and Danny Grewcock are also worries for England's very important game against South Africa on Saturday.
