Erin Routliffe is likely to pull out of New Zealand's Fed Cup group-two tournament opener against Lebanon with a groin injury.
The 22-year-old Routliffe, who won an ITF Futures event in Egypt last week, was set to lead the Kiwi charge in Bahrain but has picked up a niggle in training.
As a result, Jade Lewis and Katherine Westbury are expected to play in the singles matches, with one of the pair to join Emily Fanning in the doubles.
Team captain Neil Carter said he'd err on the side of caution with Routliffe, with a more difficult assignment to come against top seeds Uzbekistan.
"She overstretched on her serve during the session and I had planned to get all the girls on court against Lebanon, but we will wait to see how she scrubs up in the morning," Carter said on Tuesday (local time).
"If we have to keep her off-court for another day, we'll do that, because we certainly want her to play No.1 against Uzbekistan's No.1, Sabina Sharipova."
Carter believed his troops could beat Lebanon despite Routliffe's absence.
Only the group winner will progress to the Fed Cup semi-finals, while the top two teams in the tournament will be promoted to Asia-Oceania group one.
They'll play Lebanon on Wednesday, followed by Uzbekistan on Thursday.
