Derbyshire have "reluctantly" released Charl Langeveldt, their Kolpak fast bowler, for the IPL after he was signed up by the Kolkata Knight Riders.

"Although we will undoubtedly miss a bowler of Charl's experience and ability for the early part of the season, I am pleased for him that he has the opportunity to play alongside the world's best in the IPL competition," Morris said. "The absence of Charl will mean that somebody else gets an opportunity to fill the gap left by one of our senior bowlers."
