London - England star Kevin Pietersen has successfully undergone surgery on the hernia which cut short his World Cup campaign, the England and Wales Cricket Board confirmed on Wednesday.
Pietersen, who was said to be "devastated" by his withdrawal from England's Cricket World Cup squad, will now focus on getting fit in time for the Test series against Sri Lanka starting on May 26.
"Kevin underwent a successful, routine operation with a hernia and an area of weaknesses repaired on the left side while a small hernia was identified and repaired on the right side," ECB chief medical officer Nick Peirce said.
"His return to first-class cricket will be determined once he commences his rehabilitation programme but we expect him to be fully fit in time for England's first summer Test starting May 26."
Pietersen had initially planned to play through the pain barrier during the World Cup but withdrew after informing management that his condition had worsened.
