Leicester's number eight Thomas Waldrom will fly out to join the England squad in New Zealand to act as cover for Nick Easter.
"Nick Easter is still suffering from a sore back so we will be bringing Thomas out as temporary cover," coach Martin Johnson confirmed.
"We've obviously spoken to Leicester and Thomas will be flying later today."
Waldrom, who was part of the extended World Cup Preliminary Squad, will arrive in at England's team base on Wednesday, September 21.
