Injury-plagued New Zealand without Jesse Ryder for one-day series

Hard-hitting batsman Ryder, 23, has failed to prove his fitness for the five-match NatWest Series following an operation on his hand and is now lined up for a return this September.

Another new Black Cap, Daniel Flynn, was due to undergo cosmetic surgery on Tuesday to replace two teeth lost after he was hit in the mouth while batting in the Old Trafford Test defeat.

And it has also emerged opener Jamie How played on in the six-wicket loss despite fracturing a finger.

"We've decided to ease back on him and bring him back through the emerging players programme, and looking towards the Champions Trophy, introduce him through some lower key cricket and get him more cricket fit," said New Zealand coach John Bracewell after it was revealed Ryder was experiencing discomfort.

"He feels it probably more with catching than anything else, in particular reverse cup where it seems to go straight through to the nerve, so he finds that increasingly uncomfortable."

Ryder was an integral part of New Zealand's 3-1 success in the one-day campaign against England earlier this year, hitting 196 runs at an average of 49.

But he ended that series controversially when he put his right hand through a window at a Christchurch bar in the early hours of the morning, severing a tendon in his index finger in the process.

He began striking soft balls with a bat last week in a bid to take his place in the limited-overs section of the tour but will now be replaced by Peter Fulton.

Left-hander Flynn was not risked by the New Zealand management after being struck in the mouth by a James Anderson bouncer in the first innings.

Without him, England were required to take only 18 wickets to dismiss the tourists twice.

But it is hoped the 23-year-old will be able to feature in the three-day match against Northamptonshire, which begins on Friday.

"I don't think he'll lack in confidence, he's a tough character and I predict a long future for his style of cricketer within our game," said Bracewell. "There was many a time he rang up from the hotel saying 'I'm getting in the taxi, I'm coming down to bat'.

"But it's a game of cricket and we were never going to put his health at risk. Every time he moved around to any great degree it followed a pattern the doctor warned us about - he would probably feel nauseous for quite some time.

"The first thing we've got to do is throw him on a bike for 30-odd minutes to see if he doesn't throw up after that."

How, meanwhile, will be among those to sit out the match at Northampton, but he hopes to get through the rest of the tour despite the break.
