New Zealand are unsure whether Daniel Vettori will be fit for their Group A clash with Sri Lanka on Friday.
The Black Caps captain's World Cup hopes were under threat when he injured knee ligaments attempting to take a catch in the win over Pakistan.
The all-rounder was given good news after a scan and had hoped to shake off the problem in time for the final pool game on March 18.
But stand-in skipper Ross Taylor believes Vettori could miss the Mumbai fixture, as well as Sunday's match against Canada.
"Dan's injury may stay the same for another couple of weeks, we are not sure," Taylor said.
Vettori's absence means Luke Woodcock and Hamish Bennett will battle it out for a starting place against the Canadians and could be in line to play against Sri Lanka.
