New Zealand could be without all-rounder Corey Anderson and wicketkeeper BJ Watling for the second Test against England at Headingley this week due to injuries.
Watling has a "50/50" chance of playing after suffering a knee problem on the opening day of the first Test, which ended in a 124-run victory for England at Lord's.
Anderson picked up a back injury and could only bowl three overs in the second innings as a result.
"BJ's not 100%, clearly his knee is still an issue," ESPN quotes head coach Mike Hesson as saying. "He struggles to push off and get a lot of power so he's a 50/50 at this stage. From Corey's perspective bowling was painful and so was fielding so we'll need to monitor that."
The second and final Test of the series will begin on Friday.
