England seamer Reece Topley ruled out of T20 World Cup with ankle injury
The 28-year-old will be replaced by fellow left-arm fast bowler Tymal Mills, who was travelling with the squad as a reserve player. Topley, who has picked up 22 wickets in as many T20 games, sustained the injury during a fielding drill ahead of England's warm-up game against Pakistan in Brisbane on Monday.
"Results of the scan on Tuesday in Perth revealed the injury," the ECB said in a statement, adding that Lancashire's Luke Wood has been added as a travelling reserve. England, T20 World Cup champions in 2010, open their campaign against Afghanistan in Perth on Saturday.
