Pat Cummins made his Test debut for Australia in 2011
Australia's Pat Cummins has been ruled out of the T20 World Cup in India and Sri Lanka because of a troubling back injury.
Test captain Cummins, 32, managed just one appearance in his side's 4-1 Ashes win over England, with his back causing him issues for more than six months.
Australia kept him in the provisional World Cup squad, but have opted for Ben Dwarshuis in the final squad, with Matt Short also left out for former Test opener Matthew Renshaw, who only made his T20 debut this week.
"With Pat needing more time to recover from his back injury, Ben is a ready replacement who offers a left-arm pace option as well as dynamic fielding and late-order hitting," selector Tony Dodemaide said.
