London: Kevin Pietersen will miss England's Test series against New Zealand in May because of the knee injury he sustained last month.
The 32-year-old did not play in last month's final Test against the Black Caps in Auckland because of the injury.
The England and Wales Cricket Board said Pietersen is recovering from "significant bone bruising" and will have a scan next week to determine when he can resume training.
England's first Test against New Zealand begins on 16 May at Lord's.
Pietersen tweeted: "Injuries are a sportsman's worst nightmare! This one is hurting me the most."
England coach Andy Flower said recently that Pietersen needed "significant rest" in order to be fully fit for a busy 2013 schedule.
Following the two-Test series, England host the Champions Trophy tournament and then compete in a five-Test Ashes series against Australia before travelling down under in the winter.
Surrey player Pietersen first experienced knee pain while fielding in the warm-up match in Queenstown at the start of the month. The problem failed to go away and he spent time off the field during the drawn first Test in Dunedin.
He scored a duck and 12 in the first Test, but recovered with 73 in his only innings in the drawn second Test in Wellington before flying home ahead of the third Test for further investigation into his injury.
