NEW ZEALAND'S chances of winning the ICC Twenty20 dipped sharply when when Jesse Ryder was detained in hospital in London and ruled out of the tournament.

======STOP SUMMARY=====

Ireland took on New Zealand in the first day of the Super Eights at Trent Bridge on Thursday without having to face this intimidating left-hander, one of the world's best strikers of a cricket ball. Ross Taylor was ruled out with a hamstring strain, but the Irish were still heavily defeated.

New Zealand called up the Otago batsman Aaron Redmond as cover. Team manager Dave Currie said the diagnosis of Ryder's groin injury remained "unclear". A spokesman added: "It now seems likely that he is suffering from a significant infection. He has been in considerable discomfort, and medical advice is that he would certainly not be able to play in the Ireland game."

Redmond, already in the UK, joined the squad immediately. He was a leading performer in the latest domestic Twenty20 competition, finishing top run scorer including an innings of 100 not out from 58 balls.
