Fast bowler Nuwan Zoysa is a doubt for Sri Lanka's first one-day international with New Zealand this weekend after dislocating a finger on Tuesday.

The Sri Lankan left-armer hurt the finger attempting a return catch off Ewen Thompson against Central Districts at New Plymouth.

A team doctor was able to put the digit back in place but Zoysa had also suffered a deep cut that needed stitching, casting doubts over his chances of playing the Kiwis on Sunday.

Tuesday's warm-up match, Sri Lanka's first on a tour that features five one-day internationals and three Tests, was later abandoned after heavy rain.

The home side batted first, making 220 for seven from 49 overs, and Sri Lanka were 20-2 in reply when the match was called off because of the persistent showers.

New Zealand Test all-rounder Jacob Oram top scored for Central Districts with 74 off 78 balls, hitting four boundaries and three sixes in a powerful display.

With Muttiah Muralitharan unavailable as he recovers from shoulder surgery, Zoysa was the pick of the bowlers, capturing 2-22 before injuring himself.

Sri Lanka lost Saman Jayantha and Kumar Sangakkara cheaply as the rain began to fall and the match was immediately called off.
