Sick Australian pace bowler Pat Cummins slept at tea during Ashes fourth test

Sick speedster Pat Cummins continues to show remarkable resilience in his second coming as a test cricketer, rolling the arm over at the MCG despite being so sick he slept at tea.

Cummins was bothered by a stomach bug throughout day two of the fourth Ashes test.

He delivered a three-over spell in Wednesday's post-lunch session, had a quick chat with skipper Steve Smith then left the field.

Cummins returned to field after four overs, continued to receive treatment and at one point doubled over in the deep as the temperature hit 35C.
