SYDNEY - New Zealand all-rounder Dion Nash has been ruled out of tomorrow's second tri-series cricket final against South Africa.

Nash suffered a side strain last night during New Zealand's heavy loss to South Africa in the first one-day final at the Melbourne Cricket Ground.

Kiwi coach Dennis Aberhart said Nash was unavailable for tomorrow's match at the SCG and it appeared unlikely he would be able to play in the third final scheduled for Sunday.

There has been no word on Nash's replacement but with the rain-affected SCG pitch expected to suit fast bowlers, the most likely candidate is James Franklin.

The Kiwis were hopeful of practising at the SCG today, if it stopped raining.
