8216;Modi demands one month play for Eng players8217;

8220;The board believed Modi had agreed that being available for 15 days of the seven-week event would be sufficient but he has set the minimum at one month. This would mean half-dozen players thought to be targeting an IPL deal,including Kevin Pietersen,might have to choose between England and IPL,8221; the report said.

Professional Cricketers8217; Association chief executive Sean Morris described the development 8220;a serious concern8221;.

8220;This development is a serious concern. We are working through this with ECB but clearly it is a concern to India and has a potential impact on English cricket. If we are the only country not to have players appearing in the IPL then that would not be a good prospect,8221; Morris said.

If the ECB gives its players a month IPL window they would miss the first Test against West Indies starting at Lord8217;s on May 6. The IPL is slated for April 10 to May 29.

Pietersen held talks with a representative of Bangalore Royal Challengers when England played their one-day match there last November but at least two other IPL franchises are reportedly interested in signing the former England captain.
