Chandigarh, April 20: International Cricket Council will have to adjust IPL in its cricket calendar otherwise it may force cricketers from many countries to opt for retirement, India's ODI captain Mahender Singh Dhoni said today.

"They will need to take this decision otherwise we may have a situation where cricketers will prefer retirement," Dhoni said here before leaving for Chennai.

He was of the view that BCCI-backed IPL, which is currently holding its inaugural T20 tournament, will become an annual feature.

Dhoni, who is captaining the IPL team Chennai Super Kings and led them to convincing victory over Kings Punjab XI in Mohali last night, felt that with so much money involved in the lucrative league, it would become difficult to stop players (from participating).

Outgoing CEO of ICC, Malcom Speed, said in Mumbai on Wednesday that there was no immediate need to carve out a slot for the IPL in the Future Tours Programme at the moment.

Speed had said the biggest challenge facing the game's administrators right now was how to integrate the T20 format with Tests and ODIs to ensure that none had to face the disinterest of the fans.

Spin legend Shane Warne, who is leading IPL T20 team Rajasthan Royals, has slammed England and Wales Cricket Board for not allowing its centrally contracted players to turn out in the League.

Dhoni saw nothing wrong in players making money by playing in the IPL, saying in some countries the players don't not earn that big.
