Australia batsman Usman Khawaja is set to miss the remainder of the Test series against New Zealand and the series opener against West Indies.
The unlucky Khawaja, 28, strained his hamstring during the third session of the second Test on Saturday.
The left-handed batsman, who has made scores of 174 and 121 in the series, is set to miss the historic day-night Test in Adelaide starting November 27.
Khawaja is also likely to be sidelined for the first Test against West Indies beginning on December 10 in Hobart.
"Usman suffered a left hamstring injury in the field yesterday afternoon and underwent scans in Perth this morning," Cricket Australia physiotherapist David Beakley said in a statement.
"The scans have indicated a moderate hamstring muscle strain which means it is likely he will be unavailable for the next two Commonwealth Bank Test matches in Adelaide and Hobart."
Shaun Marsh and Cameron Bancroft appear the most likely to come in and replace Khawaja.
