Those injuries can’t be put down to fitness. However, the other injuries show that the level of match-fitness of the players is not good enough.
Compared to India, the Australians had lost only David Warner to soft tissue injury — groin — in the Test series and he has somehow regained fitness to play the last two Tests.
Importantly, Australia’s four front-line bowlers — Mitchell Starc, Josh Hazlewood, Pat Cummins and Nathan Lyon — have bowled 435.1 overs in the first three Tests and are fit enough to play the fourth Test.
