Jan 31 (Reuters) - Australia fast bowler ‌Pat Cummins was ruled out on Saturday for next month's Twenty20 World ‌Cup after failing to recover from a nagging back injury, and Ben ‌Dwarshuis will replace him for the global showpiece.

Cummins played just one of the five Ashes tests against England, but Australia kept him in the provisional World Cup squad hoping for his availability in ‍the Super Eight stage of the tournament to be ‍played in India and Sri ‌Lanka.
