Teenage paceman Pat Cummins will miss the start of Australia's test series against India after scans revealed his heel injury is more serious than initially diagnosed.
The 18-year-old Cummins injured his left heel in the second test against South Africa last month when he took six second-innings wickets and hit the winning runs in a man-of-the-match performance on debut at Johannesburg.
He was ruled out of the ongoing two-test series against New Zealand with a suspected soft-tissue injury.
But Australia team physiotherapist Alex Kountouris on Wednesday said a specialist had subsequently detected a bone stress injury, meaning Cummins was unlikely to resume bowling until early to mid-January.
The four-test series against India starts Dec. 26 at Melbourne and continues with matches in Sydney, Adelaide and Perth.
