Australia heaved a major sigh of relief on Wednesday after skipper Pat Cummins declared run-machine Travis Head fit for the Boxing Day test against India at the Melbourne Cricket Ground.

Australia run-maker Travis Head is questionable for the fourth cricket test against India at the Melbourne Cricket Ground, and teenager Sam Konstas is set to make his first test start for the home side.

Australia are sweating on the fitness of Travis Head after the star batter failed to fully train two days out from the Boxing Day Test.

In-form Australian batter Travis Head will be fit for the fourth test and India are considering restoring captain Rohit Sharma to the opener's slot for the match starting in Melbourne on Thursday. Head is the leading run scorer in the five-test series but the left-hander suffered a quad strain in Brisbane.
