Experienced Crow Courtney Cramey could miss up to four weeks after suffering a hamstring strain to her left leg on Saturday night.

The defender sustained the injury in the second quarter of Adelaide’s 42-victory over Fremantle and did not return to the match.

“Scans have come back showing a grade two strain, which means Courtney is likely to be out for 2-4 weeks,” Crows Physical Performance Coach Brad Newton said.

“Hopefully she will be ready to return in Round Seven, but we will make a call that week.”

The Crows will take on North Melbourne at Avalon Airport Oval on Sunday afternoon.
