Geelong forward Cory Gregson has suffered a midfoot sprain, which will see the youngster out of action indefinitely.

Scans confirmed the injury after Gregson left the field during his side’s win over St Kilda on Sunday, although Geelong’s General Manager of Football Simon Lloyd said the forward remained in good spirits following the diagnosis.

“Cory is in good spirits with a positive mindset, he will begin weight bearing on the foot over the coming days which is a great outcome,” Lloyd told geelongcats.com.au.

Defender Lachie Henderson also underwent an arthroscope on his knee on Tuesday, which has set back his recovery time.

The Cats are confident they can get Henderson back on the park later in the year, as he remains a vital component of their backline.

“Lachie’s knee surgery went as expected, we believe this will allow him to return to football later this year,” Lloyd added.

“Lachie continues to remain focussed on doing all he can to get back to football and will work closely with the club’s medical team on the next steps in his rehab.”
