Wellington: New Zealand cricket suffered twin blows on Sunday with injured captain Daniel Vettori ruled out of the Twenty20 series against England and Scott Styris retiring from Test cricket.
Vettori, who rolled an ankle during training last week, said the injury was improving but he would not participate in the Twenty20 games in Auckland on Tuesday and Christchurch on Thursday.
He was also in doubt for the opening one-day international against England next Sunday but would undergo a medical assessment later in the week.
Experienced middle-order batsman Scott Styris announced his retirement from Test matches, saying he wanted to focus on the limited over versions of the game with the 2011 World Cup in India as his end goal.
"The rigours of international cricket have become increasingly demanding and I would like to extend my career by focusing on shorter versions of the game," the 32-year-old said.
"I have found the niggles and injuries associated with the longer form of the game were making it difficult for me to get on to the park."
In his 29-Test career, Styris scored 1,586 runs at an average of 36.04 and also proved a handy medium pacer taking 20 wickets at 51.15
England meanwhile won their opening warm up match in New Zealand -- a 50-over encounter against Canterbury -- by 51 runs on Saturday.
Ian Bell topscored with 79 off 89 deliveries while Alastair Cook compiled a brisk 51 and Kevin Pietersen made 48.
