Ryder, who last played for New Zealand on January 31, has a contract with the Melbourne Renegades in Australia's Big Bash League, which starts on December 18. He is expected to play four Ford Trophy 50-over games from late December for Otago. That amounts to his only worthwhile 50-over lead-up before the Cup squad is named on January 8.
Otago Cricket chief executive Ross Dykes said yesterday that it was hoped Ryder, 30, would be available for Otago's next Georgie Pie T20 game against Canterbury in Dunedin on Thursday.
Dykes confirmed Ryder's teammates wanted him to join them in Christchurch on a later flight in time for Sunday's game.
"He was really keen to get up there and play, but wasn't sure whether he could do himself and the team justice."
In an ironic twist, Otago had their first win for the competition, by one run, over Canterbury without Ryder.
Edgar said they might not replace Ryder in the group flying to Dubai tomorrow , because they had sufficient cover from the test squad now playing Pakistan there.
