England's Sam Curran ruled out of T20 World Cup
Curran noticed the problem after playing for Chennai Super Kings in their Indian Premier League match against Rajasthan Royals on Saturday.
Scans revealed the Surrey left-hander's injury and he will fly home for further tests and a full review with England's medical team.
With the injury expected to sideline him for several weeks, Curran's brother, Tom, has been called into England's squad to replace the 23-year-old.
Surrey's Reece Topley has been added as a travelling reserve and will join the England party in due course.
They face warm-up matches against India and New Zealand before kicking off their tournament against the West Indies on October 23.
