Australia coach Andrew McDonald has revealed the extreme risk selectors took with captain Pat Cummins, who starred in the third Ashes Test in Adelaide on his return to the side, but has now been ruled out for the rest of the series.

McDonald and the other selectors named a 15-player squad on Tuesday for the Boxing Day Test, which includes back-up pace trio Jhye Richardson, Brendan Doggett and second Test hero Michael Neser, as well as Victorian off-spinner Todd Murphy as a replacement for the injured Nathan Lyon.
