Otago ouhalf Nick Evans has been drafted into New Zealand's squad for their tour of Ireland and Britain. Evans replaces Luke McAlister, who is due to undergo knee surgery on Friday - the day his team-mates arrive in Cardiff ahead of their November 5th match with Wales - and could be out for eight weeks.

Prop Greg Somerville could also miss the tour after tearing a calf muscle earlier this month.

Auckland forward Saimone Taumoepeau has joined the training camp as cover, and a final decision on Somerville's fitness is likely to be made today.

"It is disappointing news for Luke, and potentially for Greg as well," said All Blacks coach Graham Henry. "The medical advice for Luke is clear - surgery is the best option. We are holding out a little hope for Greg, but he is in a race against the clock and we need to see significant improvement."

Lock Ali Williams looks like missing the Wales encounter due to shoulder trouble but should be available for the November 12th appointment with Ireland.
