New Zealand captain Daniel Vettori hurt his right knee while attempting a catch in his team's World Cup Group A match against Pakistan at Pallekele stadium in Sri Lanka on Tuesday.
The 32-year-old landed awkwardly as he tried to catch Kamran Akmal at mid-on after New Zealand set Pakistan a mammoth 303-run target. He was helped to the dressing room by team officials.
"Dan hurt his right knee while attempting a catch. He is currently taking ice treatment and was being assessed," team media manager Ellery Tappin said.
Vettori has a history of back and knee injuries in a career spanning more than 14 years.
New Zealand made 302-7 after winning the toss, with Ross Taylor hitting a career-best 131 not out.
