Sri Lanka's team management is concerned over the health of former skipper Sanath Jayasuriya after his fourth bout of tonsillitis in three months.
Jayasuriya stayed in bed and missed practice on Sunday after suffering with what manager Ajit Jayasekera described as "a severe fever."
Jayasuriya was plagued with tonsillitis during the Super Six stage of the World Cup and was laid low again during last month's Sharjah Cup.
He is expected to play in the tri-series game against New Zealand on Tuesday but Jayasekera said: "We are concerned by the number of times that he has been laid low by tonsillitis. This is the fourth time since the start of the World Cup."
Officials hope Jayasuriya will be able to practice on Monday ahead of Tuesday's match.
