Geelong midfielder Mitch Duncan will miss an extended period after a MRI confirmed he suffered a PCL injury in Friday’s win over the Bulldogs.

“We were expecting that the injury was to Mitch’s PCL, and the scan confirmed that,” Geelong’s general manager of football Simon Lloyd said.

“There was no other damage to Mitch’s knee. The rehabilitation timelines will be further discussed with our medical and fitness team in consultation with specialists.

“We will explore all available options that will allow Mitch to return as quickly and safely as possible.”
