Morris had taken his first two ODI wickets in a fiery spell to leave West Indies in tatters as they were bowled out for 86. But three balls into the fifth over of his first spell, having claimed 2 for 13 with a maiden, he felt pain in his left side and immediately grabbed his cap and headed off the ground to get assessed.
Cricket Australia confirmed shortly after that Morris had suffered a left side strain and would head for a scan at some stage to determine the extent of the injury.
It leaves Morris in doubt for the two-Test tour of New Zealand which starts in Wellington on February 29, although there was a chance Morris would not be required despite travelling with the Test team through the early part of the Australian summer.
Morris is yet to make his Test debut but was carefully managed through the early part of the Australian domestic summer to be fit for the Pakistan Test series. However, he was not required as Pat Cummins, Mitchell Starc and Josh Hazlewood played all five Tests against Pakistan and West Indies without issue.
Australia is expected to name their Test squad for the New Zealand series later this week.
