New Zealand are down to a bare bones 13 for their one-off test against Zimbabwe, starting in Bulawayo tomorrow night.
Having lost seamer Kyle Mills to a groin injury last week, middle-order batsman Jesse Ryder is heading home after suffering a right calf strain.
The lefthander and occasional medium pacer pulled up after delivering just three balls during New Zealand's two-day warmup game against Zimbabwe yesterday. A scan confirmed the injury.
Team manager Mike Sandle said Ryder would undergo a period of rehabilitation upon returning to New Zealand.
The first of two tests against Australia starts in Brisbane on December 1 and Sandle said New Zealand's medical team were confident Ryder would be fit again in time for that assignment.
