New Delhi, Mar 27 (cricinfo): Fast bowler Ishant Sharma has been ruled out of the IPL after undergoing an ankle surgery earlier this month, which is likely to keep him out of action for at least six months. Deccan Chargers, Ishant's IPL franchise, confirmed the development, saying they would now be seeking permission from the IPL for a replacement player.

Ishant had been delaying the surgery for nearly a year, but finally decided to take the plunge after he returned from Australia in January, where he had played the Test-leg of the tour. Though he impressed in patches, Ishant remained inconsistent and only managed five wickets at an average of 90.20 in the four-Test series.

It is understood that he had considered delaying the surgery post this IPL season, but that would have ruled him out of the home series against England, starting in November. Ishant is likely to plan his rehabilitation so that he can make a return during the home series against New Zealand, also later in the year.

"The wound is likely to heal in three months' time and he is solely focusing on that," a source close to Ishant told ESPNcricinfo.

Last year, Ishant's India team-mate Virender Sehwag was in a similar scenario with a shoulder injury but he chose to delay his surgery. After the World Cup, he played through pain at the start of the IPL but withdrew midway through the tournament. He was ruled out of the West Indies tour and missed the start of the Test series in England.
