The pace bowler increased the injury concerns plaguing England when he left the field early on day two in the Melbourne Test versus the Australians.

The concluding match of the series at the SCG starts this coming Sunday.
The visitors have previously lost strike bowlers Mark Wood due to knee trouble and Jofra Archer with an abdominal strain on the current trip.
A replacement bowler was added to the party to provide backup.

After bowling one over late on the first day, he returned on Saturday morning and removed Scott Boland Scott Boland caught behind.
However, on the final ball of his spell, he bowled a variation to Travis Head and suddenly grabbed his left hamstring.
