Reece Topley is an injury doubt for England's first game of the T20 World Cup against Afghanistan on Saturday.

The left-arm paceman rolled his ankle during a fielding drill ahead of Monday's warm-up win over Pakistan at the Gabba.

Topley will be assessed before Jos Buttler's side take on Afghanistan in their Group 1 opener at Perth Stadium.

England will face a qualifier in their second World Cup match next Wednesday, then face hosts Australia two days later.

The quick has made an impressive return to the international stage after fears his career could be over due to back injuries.

Topley played in all three of England's matches in the recent T20I series win over Australia, having featured in four of the seven games in the 4-3 victory in Pakistan.
