Dernbach is currently with England Lions in the West Indies
England have called up Surrey pace bowler Jade Dernbach to their World Cup squad following the hamstring injury suffered by Ajmal Shahzad.
The 24-year-old is currently in the West Indies as part of the England Lions set-up and is the side's leading wicket taker.
National selector Geoff Miller said: "We have been following the progress of Jade for some time.
"We feel his variations will be extremely useful."
Dernbach began the winter on the England Performance Programme in Australia before going on to make his England Lions debut last month, featuring in the WICB regional four-day competition.
The South African-born player spent the previous two winters on the England Cricket Board [ECB] Fast Bowling Programme in Florida and Chennai and is a graduate of the Surrey academy.

Batting average: 8.64
Bowling: 95 wkts @ 27.28
The ICC Event Technical Committee has given their approval for his inclusion in the squad after Shahzad
was forced to withdraw on Thursday.
England are awaiting confirmation that they have reached the quarter-finals of the World Cup - their progression is dependent on the remaining matches in the group stages.
Surrey coach Ian Salisbury told the club's website: "I'm really really pleased for him. It proves his development over the last two years has been excellent and is just reward for some very hard work. He's a big match player and it won't phase him at all to play on a stage like the World Cup."
Dernbach made his Surrey debut in 2003 at the age of 17 and has made 143 appearances for the county in all formats.
He is the joint second highest wicket taker in the WICB four-day competition this year with 19 at an average of 15.63. He was selected in the Lions side to face the Windward Islands on Thursday and was the only player not to bat as the Lions
finished on 280-8 at the end of the first day,
but will now fly out to join the England side in Delhi.
