Tim Southee and Rob Nicol will not travel with the team to Kandy today following an illness picked up on the Black Caps' ICC World Twenty20 campaign in Sri Lanka.
Southee reported to medical staff that he felt unwell yesterday morning before the nine-loss to and subsequently displayed symptoms associated with gastro-enteritis.
Nicol was sick over-night and could not travel comfortably today so will also remain in Colombo under observation of the team doctor.
Because Southee showed signs of dehydration it has been decided that he will receive re-hydration treatment at the local hospital.
If sufficient improvements are made today the pair will travel to Kandy later today.
Daniel Vettori, who was also ruled out of yesterday's warm-up match due to illness, has improved and is travelling with the team today.
The Black Caps open their T20 World Cup campaign against Bangladesh at Pallekele International Cricket Stadium on Friday night.
